Southampton boss Ronald Koeman admits Toby Alderweireld's injury could force them back into the market.

Ideally, Saints would not add to their squad with another central defender but Koeman admitted the club will have to weigh up what to do once they know how long Alderweireld is out.

He said: "I don't know (if we need to sign another centre half), we have to speak about that.

"We know that Maya will be away for some weeks, we know that. "We knew already if we get some injuries then maybe it can be a problem but I think in our squad we can do some changes in positions to keep going."
