Southampton are reportedly prepared to challenge Manchester United for the services of Stefan de Vrij.

The Netherlands international has 12 months left to run on his contract with Feyenoord, who have accepted that the centre-back is likely to depart De Kuip this summer.

New United boss Louis van Gaal is thought to be an admirer of the 22-year-old, having coached him during his recent stint in charge of the Dutch national side.

However, Saints boss Ronald Koeman has identified De Vrij as the ideal replacement for Liverpool-bound Dejan Lovren, according to The Mirror.

It is believed that De Vrij would command a fee in the region of £8m.
