There is a reason goalkeepers tend to stay in goals.

Petr Cech looks set to miss Arsenal's North London derby with Tottenham on Sunday after injuring his hamstring after running up for a corner late in the 2-1 loss to Swansea on Wednesday night.

The Czech goalkeeper injured himself in the final moments of the game as Arsenal missed the chance to move to within three points of leaders Leicester City. Afterwards, Arsenal manager Arsene Wenger confirmed that Cech will be replaced by Colombian international David Ospina on Sunday.

Cech has started all but one of Arsenal's Premier League games this season. The 33-year-old has more clean sheets than any other goalkeeper in the league this season.
