Premier League: West Ham boss Sam Allardyce warns Sunderland there's more to come from Andy Carroll

West Ham manager Sam Allardyce has warned Sunderland there is more to come from Andy Carroll after the England forward's man-of-the-match display last time out.

The former Newcastle and Liverpool striker scored twice in the 3-1 home win over Swansea to lift the Hammers to fourth in the Premier League table.

The goals were the first of the campaign for Carroll who had been sidelined for four months after suffering an ankle injury in pre-season. 

Whoever scores them, let's keep scoring them

Allardyce said: "I don't think he is as good as he can be, on the back of a long lay-off and a handful of games back in the team.

"The overall performance first and foremost and, more importantly, the goals will give him a massive boost in confidence.

"I think we're the third highest goalscorers in the league at the minute. Let's keep doing that. Whoever scores them, let's keep scoring them.

"I said, before Andy scored, the last nine goals had nine different goalscorers, prior to the Swansea game, so there are a lot of goals being shared all over.

"There is also Enner Valencia, with the likes of Andy and Diafra Sakho, Carlton Cole and Mauro Zarate. It's a very, very good strong front line."

Allardyce admitted a spot in the top-four was beyond his wildest expectations at the start of the season and added: "I wouldn't have thought it was achievable before we started playing because we had so many new players. 

"But like I've said many times the new players have done a particularly fantastic job. The other players have done a job to welcome them in and make them feel comfortable. Our team spirit and family feel has played a part and everyone is on top of their game."

The Englishman revealed, however, that he had not begun to envisage qualifying for the Champions League for the first time.

He said: "If we're still here towards the end of January then we'll reassess our aims. By that point we'll have played 20 games, we'll have played everybody once so we should have a good indicator of where we are.

"We'll see what everybody has got in their locker, everybody would've seen what we have in ours so it'll be a question of whether we can carry it on.

"We might have a little worrying spell during the Africa Cup of Nations in January, that's why I'm not prepared to do any more predictions until they come back."
