Manchester United are holding tense internal discussions about a move for Tottenham defender Toby Alderweireld.

Alderweireld's contract allows him to leave for £25million this summer, with United among his admirers, says The Sun.

United boss Ole Gunnar Solskjaer would prefer to retain his current centre-backs and use his coaching ability to turn their form around.

But United are refusing to rule out an approach, especially given the reasonable fee for the Belgian international, 30.

The Red Devils are looking for defensive reinforcements as they failed to keep a clean sheet in their final 15 games of the season.

But Alderweireld, who is also on Arsenal's radar, still expects to stay at Spurs next season for the final year of his contract.
