CECH: CORRECTION MARKS

Petr Cech has discussed the set-piece double that sunk Chelsea at Villa Park and saw a combination of misfortune and errors as the cause of the goals.
Two corners headed in by Aston Villa wiped out our 14^th minute lead and set up a second defeat of the season.
The home side's first goal was converted by Richard Dunne after skimming off the head of Frank Lampard at the near post. The second was headed in by the other centre-back, James Collins, having cleared Cech and reached him directly.
'There was an unlucky deflection for the first one and when this happens it is difficult to control it,' explained Cech. 'The second one we didn't mark well but as well when I went for the ball, I clipped someone in front of me which is why I couldn't reach the ball. Otherwise I would have reached it and then put it into safety.
'It might have even been my team-mate, but just before I wanted to get hold of the ball, I clipped him.
'The last two away games we've conceded three goals from set plays so we need to get our discipline with marking and avoid these goals, because they can be costly,' the keeper continued.
'At the moment we are a little bit unlucky as well, but we know we have to pay more attention and have better concentration next time.'
The match saw Cech return having served a suspension against Liverpool and it began well enough.
'We expected Villa to start strong and to put a lot of pressure on us but then exactly the moment when it was happening we went 1-0 up,' he said.
'That was exactly what we needed so that was a good moment of the game. Then of course they tried to put us under pressure. Unfortunately for us we concede before the end of the half and it was disappointing because it was a set-piece and until then we had defended set-pieces and crosses very well.
'The second half was more or less the same story , we made a mistake at the corner and when they went 2-1 up it was better for them because they could defend, they could wait for the counter attack and they have good players up front.
'We created some chances and it was a pity we didn't take them. We needed just a little bit more luck to score the goal.'
The two away league defeats have been tough to stomach in a season that is otherwise going so well, but there is no panic yet among the playing staff.
'It is a pity we gave Man United the chance to go a point ahead but the most important is always the correction,' points out Cech. 'We have another game on Wednesday and then Blackburn at home and we need to make sure we win those games.
'If you finish the season with two defeats it doesn't matter if they are in the first 10 games or the last 10 games. These two defeats we will judge at the end of the season if they were really costly.'
