Manchester United's deal for Napoli defender Kim Min-jae remains on track.

The South Korea international is said to have agreed personal terms with United, which are willing to meet his €60m buyout clause.

However, doubts have emerged that Kim will make the move with Napoli eager to open new contract talks - along with rival interest from PSG.

But Il Corriere dello Sport says it is 'almost certain' that Kim will leave Napoli for Old Trafford this summer.

It's suggested United are now stepping up talks with the season over in both countries.
