Arsene Wenger: ‘Clever’ Diego Costa has got two Arsenal players sent off this season

“Costa got two of our players sent off in the last two games against Chelsea. Those are only facts.”

Arsene Wenger bemoaned the influence of Diego Costa as the Chelsea striker once again proved a thorn in 10-man Arsenal’s side.

Costa in September tussled with Laurent Koscielny and Gabriel, who was sent off, and on Sunday drew a foul from Per Mertesacker which saw the German dismissed at the Emirates Stadium in Chelsea’s 1-0 win.
