Arsenal boss Mikel Arteta says their buying this month may not be over.

Arsenal have signed Belgium striker Leandro Trossard from Brighton and Poland defender Jakub Kiwior from Spezia Calcio during the January transfer window.

Arteta said they could still sign a midfielder this month too, with Mohamed Elneny ruled out indefinitely because of a knee injury.

"We need some more cover in midfield ideally if we can," he added. "In this market it's pretty complicated to do that.

"The most important thing is that we get the performances and the time on the pitch that we need, with the players we have available that are already really good."
