Manchester United are believed to be closing in on their fifth summer signing as the Red Devils are set to agree a fee for Ajax teenager Timothy Fosu-Mensah, according to Goal.com.

The 16-year-old was part of the Dutch side during the AEGON Future Cup tournament in April. Fosu-Mensah was one of the star players of the tournament where United were defeated by Ajax in one of the matches.

Ajax won the Future Cup for the third time this year. Fosu-Mensah impressed during the Future Cup and has been touted to make a move to one of Europe's top clubs this summer.

The player's versatility of playing either as a left-back, central defender or a left-wing has attracted interest from clubs across the continent. The teenager has been chased by United's derby rivals Manchester City and Italian giants Inter Milan.

The defender was spotted at United's Carrington base as Fosu-Mensah was set to undergo a medical before his proposed move to Old Trafford ahead of deadline day. The deal will see Louis van Gaal's side pay a compensation of £300,000 to Ajax.

United have already signed four players this summer as they have added Ander Herrera, Luke Shaw, Marcos Rojo and finally Angel Di Maria. The Argentine international arrived at Old Trafford from Real Madrid for a British record fee of £59.7m.

If a deal for the Dutch-born Ghana defender progresses, Fosu-Mensah will be United's fifth signing of this transfer window.

Meanwhile, United make a trip to Turf Moor for their next league fixture against Burnley on Saturday. Ashley Young says the Red Devils are working hard to find their first win of the season.

"It's obviously disappointing that we've only got one point on the board but it's like the manager has said - you've got to believe in his philosophy which all the players are doing," Young told United's official website.

"It's not going to take a day or a week or a month, it might take longer but we're working hard in training and we're trying to play the manager wants us to."

"It's about getting the results now and we've got another opportunity to do that on Saturday. The way we've trained this week I'm confident everything will click into place and we can get the three points and kick on from there," he added.
