Arsenal goalkeeper Petr Cech apologised for his howler in defeat at Swansea City.
Cech has issued an apology on Twitter as his error contributed to a 3-1 defeat against relegation battlers Swansea on Wednesday night.
The defeat leaves Arsenal eight points behind fourth place Liverpool, with the possible arrival of striker Pierre-Emerick Aubameyang from Borussia Dortmund dominating Wenger's post match press conference.
Although mistakes are part of the game I always expect 100 % from myself and I’m not happy with the one I made today ... back to work tomorrow ! — Petr Cech (@PetrCech) January 30, 2018
