Ange Postecoglou admits Tottenham may be forced to make a move over the weekend for defensive cover if Radu Dragusin's injury turns out to be serious.
Dragusin came off with a knee injury after coming on as a half-time substitute during a 3-0 Europa League win against Elfsborg on Thursday.
Postecoglou thought it did not look too good after the match and although he will wait for further information he is already thinking of contingency plans with the transfer window closing on Monday.
'Depending on the extent of Radu, it might be an area we need to look at and certainly this weekend we are exploring some options,' said the Spurs boss, ahead of Sunday's Premier League game at Brentford.
