Saka was already an injury concern ahead of Arsenal\u2019s trip to Lens after issues against both Tottenham and Bournemouth, but Arteta said he did not regret his decision to start the forward in France.<\/p>\n
\u201cNo,\u201d Arteta said, \u201cit was a knock that he had the other day and he was perfectly fine. It was a back-heel, an action that can produce that kind of injury.<\/p>\n
\u201cLet\u2019s see what the extent of it is and afterwards it\u2019s too late. The last few were more knocks than anything else.<\/p>\n
\u201cHe hasn\u2019t really missed games. We gave him a break against Brentford (in the Carabao Cup) last week and that was all.<\/p>\n
\u201cHe tried to backheel a ball in the first half and felt something muscular. He felt uncomfortable to carry on so we had to take him off.<\/p>\n
\u201cWe don\u2019t know anything more. It was big enough not to allow him to continue to play the game and that\u2019s a worry for us.\u201d<\/p>\n
