Arsenal may have slipped up at Southampton this week and seen Manchester City take over at the Premier League summit but there are plenty more twists in this title race to come.
Tough
Palace, though, have turned their fortunes around significantly since Tony Pulis arrived at the club.
I played in midfield with Tony at Bournemouth and he was an animal in those days. He was one of the most incredible tacklers I've ever seen, a fearless player and someone who I knew would become a manager because of his mentality and the way he thought about the game.
And he's had success on the touchline, too. He's never been relegated as a manager and we all know what he did at Stoke to establish them in the Premier League.
A couple of months ago it seemed as though Palace and Sunderland had it all to do and we were wondering who would go down with them. Well, now it looks like they're certainties to stay up and it's thrown everybody else into the equation.
This time last year Reading and QPR were cut adrift but this season that's not been the case. It's so tight - and it's going to be a horrible situation for those clubs involved.
Pulis has obviously been a big part of Palace's revival - they've won five and drawn one of the 11 games he's been in charge of - but they are creating something similar to what he had at Stoke there now, which started to take shape under previous boss Ian Holloway.
Opposition teams go there and think 'I'm not looking forward to this'. The small dressing rooms, the loud crowd, the home team's style of football - it all adds up to make Selhurst Park a tough place to go.
The problem they have is Man City, Man United, Chelsea and Liverpool are all due to visit before the end of the season.
When I was relegated with Southampton one of the big reasons we went down was because we had to play the top six at home towards the end of the campaign. Palace are in a similar position and that could spell danger for them.
But they have been grabbing some important 1-0 wins recently and they've given themselves a good chance of surviving in the Premier League for the first time in their history.
They won't make it easy for Arsenal on Sunday, either - but I expect the hosts to come through and win 3-1.
