Manchester United boss Louis van Gaal says their market plans are well underway.

United have been heavily linked with Mats Hummels and Ilkay Gundogan of Borussia Dortmund, PSV Eindhoven's Memphis Depay, Gareth Bale of Real Madrid and lately Burnley striker Danny Ings.

"This summer is very important, of course. We need balance in our selection. I cannot deny that. But we are very busy with that," LVG says.

"I am looking for players who fit in as my players, so that has to be a quicker adaptation than players who I have received when I came here in Manchester United."
