Martin's starting stats

I was at Leicester's astonishing draw with West Ham on Sunday. You can trace Leicester's rise from bottom to top to last April when Leicester beat West Ham 2-1 to start a run of seven wins from nine to steer them clear of relegation.

West Ham won their first away Premier League penalty since November 2010 at Wolves when Mark Noble scored - but he had been taken off on Sunday, so Andy Carroll had to take it in his place. Carroll's first ever goal in senior football was against Leicester for Preston in November 2007. Sunday's was his 42nd Premier League goal - 21 of which have been headers and this was only his second penalty.

Sunday's other penalty was Leicester's 11th of the season scored by Leonardo Ulloa. The other 10 have been shared between Jamie Vardy (scored four out of four) and Riyad Mahrez (four out of six). All 11 penalties have been on target (Mahrez has had two saved).

Amid the mayhem, both Leicester and West Ham extended unbeaten runs to eight Premier League games. West Ham have no wins in their last six in all competitions (but five of those were score draws).

Aaron Cresswell had lost 6-0 with Ipswich at the King Power in November 2012 - but his goal helped him get some redemption for that. Despite the proximity of defeat, Leicester extended their home unbeaten record to 13. It wasn't quite unlucky 13 for them!

Three Premier League strikers are currently chasing records held by Gary Lineker. Jamie Vardy is chasing Lineker's total of 24 in 1984/85, which is the previous time a Leicester player scored more than 20 in the top division. Harry Kane has 24 goals this season and the last Spurs player to score more was Lineker with 28 in 1991/92. Romelu Lukaku has 18 goals and Lineker was the last Everton player to score more than 20 when he got 30 league goals in 1985/86. 

Red gloves

Is Courtois the first goalkeeper to be sent off twice in a PL season? Tom, Richmond

MARTIN SAYS: The Belgian goalkeeper joined a six-man club of goalkeepers who have received two red cards in a single season, following his sending off on the opening-day draw with Swansea and another in the 3-0 defeat by Man City on Saturday Night Football.

Neville Southall (1992/93), Pavel Srnicek (1994/95), Jussi Jaaskelainen (2001/02), Maik Taylor (2003/04) and Allan McGregor (2013/14) were also sent off twice in a single Premier League season.

The two reds this season are Courtois' only two in his Premier League career, and he has some way to go to top the unwanted all-time list.

Srnicek and Jaaskelainen sit top of that unwanted table with four red cards each, ahead of Taylor and Tim Flowers (three reds).

Adrian, Shaka Hislop, Russell Hoult, Simon Tracey, McGregor, Southall and Jose Reina join Courtois on two.

Top of the drops             

Has any team dropped more points from one season to the next than Chelsea? Jimmy, Reading

MARTIN SAYS: The humbling defeat by Man City on Saturday means Chelsea are now 33 points worse off than at this stage last season, and they are on course for the biggest points drop in Premier League history from one season to the next.

The record is held by Ipswich, who ended up 30 points worse off as they were relegated in 2001/02 with 36 points having finished fifth the season before with 66 points, where they qualified for the UEFA Cup.

Even if Chelsea win their five remaining games they will still be 28 points worse off than last season. If they pick less than 13 points then they will set a new record.

The next biggest drop is 25 points. Everton dropped 25 points from 2013/14 to 2014/15 (72 points to 47), while Manchester United also surrendered 25 points from winning the title in 2012/13 to finishing seventh on 64 points in 2013/14 under David Moyes.

It's worth pointing out that Leeds (30), Blackburn (28) and QPR (27) suffered big points drops in the 1995/96 season - but that's partly because they played four games fewer than in the previous season. In the last season before the Premier League started,

I will also add that Leeds won the title with 82 points in 1991/92 and in the first Premier League season they finished 17th with 51 points - a drop of 31.

In 1954/55 when Chelsea won their first title they would have had 72 points if it had been three points for a win. The following season they finished 16th with the equivalent of 53 points. Older Chelsea fans will remember that a collapse after winning the title is not new!

Spot of bother

Saido Berahino missed two penalties against Watford, has anyone missed more in a Premier League game? Paul, Hitchin

MARTIN SAYS: Berahino has become the fourth player to have missed two penalties in a Premier League game when Watford's Heurelho Gomes denied him twice from 12 yards on Saturday.

No player has ever missed three penalties in England's top-flight, although Darren Bent has come close. He took three penalties for Sunderland against Tottenham in 2010 and was thwarted twice, incidentally by Gomes, but managed to score with his first attempt at the Stadium of Light that day.

The first player to miss two penalties in a Premier League game was Leicester City midfielder Mark Draper, who twice failed to find a way past Newcastle goalkeeper Pavel Srnicek in a 3-1 defeat on the opening day of the 1994/95 season.

The only other player to feature on this list is Juan Pablo Angel. After heading Aston Villa into the lead at Fulham in February 2005, the Colombian missed two chances to extend his side's lead as Edwin van der Sar kept two of his penalties out. Things then went from bad to worse for the Villans as Lee Clark hammered home an injury time-time equaliser as the Cottagers snatched an unlikely point.

Paying the penalty

Norwich have conceded nine penalties this season, what's the record in a single PL season? Chris, Dereham

MARTIN SAYS: Alex Neil's side have had their fair share of penalty decisions go against them this season, with the Canaries two short of the record for penalties faced in a Premier League season.

Andre Wisdom's foul on Fabio Borini in Saturday's relegation battle at Carrow Road saw referee Andre Marriner award a ninth penalty against Norwich this season, with Borini dusting himself down the become the eighth of those to convert from 12 yards.

Norwich are the ninth team to have conceded nine penalties in a Premier League season but, with four games remaining this season, there is still time to catch the four clubs to have conceded more.

One more spot-kick would see them draw level with Nottingham Forest (1998/99), Fulham (2002/03) and Bradford City (1999/00) on ten, while another two would see them equal Blackburn Rovers' tally of 11, recorded in 2006/07.
