Arsenal goalkeeper Petr Cech has urged David Ospina to put his midweek howler against Olympiacos behind him.

Cech watched from the bench as Ospina’s error at the end of the first half left Arsenal trailing before they were eventually beaten 3-2 by the Greek side to put their Champions League hopes in jeopardy.

The former Chelsea stopper thinks the Gunners’ lack of game management contributed more to the defeat rather than Ospina’s mistake.

“The biggest blow was we allowed them to score one minute later after coming back to 2-2,” Cech told talkSPORT.

“This was where the game was decided. We probably went too much with emotion instead of going back to basics after that goal.

“You always try to help your team-mate in a situation like this because I’ve been in the same situation a few times and you need to make sure the next day you put it behind you and you come back to work and get ready for the next game because you can’t change it.”

The former Chelsea man believes his new club need to find a ruthless edge if they are to challenge for honours this season, starting with this Sunday’s clash with league leaders Manchester United.

“We dropped points in the games you think you could have done better,” said the 33-year-old.

“If we avoid games like that and if we keep winning and putting points on then I think the quality and experience of the team to challenge for the title.

“The important thing is that it’s a game for six points, they [Manchester United] are top of the league and we are three points behind. If we want to close the gap we need to win the game.

“After what happened on Tuesday there is more pressure on us to do well and bounce back from a huge disappointment and we need to make sure we are ready.”
