Manchester United have signed FIFA World Cup midfielder Youri Tielemans from Premier League rivals Aston Villa but they are not done in the transfer market.

United triggered Tielemans’ $67million AUD release clause to prise the Belgium international from UEFA Europa League holders Villa.

The 29-year-old has signed a five-year contract at Old Trafford, where United unveiled Brazilian midfielder Andrey Santos in a $96m AUD deal earlier in the week before announcing the arrival of goalkeeper Karl Darlow.

“It’s hard to describe just how proud I am to join Manchester United. Signing for such a special club feels incredible, it is the culmination of years of dedication since I first fell in love with football,” Tielemans said.

“I have had the privilege of experiencing success in the game and it has only increased my determination to achieve more. The ambition from everyone at the club is extremely clear; we are all determined to push for the biggest trophies over the coming years.”

According to Manchester journalist Samuel Luckhurst, United still want to add a third midfielder, a left winger and a forward to strengthen their attack behind Benjamin Sesko.

It comes as Fabrizio Romano reports United have contacted the agent of Roma and France midfielder Manu Kone amid their pursuit of a defensive midfielder.

“Youri has consistently been one of the most outstanding midfielders in the Premier League throughout the past seven years. He has all of the technical qualities, as well as the ambition and mentality, to thrive at Manchester United,” said United’s director of football Jason Wilcox.

“Youri’s consistency is exceptional, and he will add further composure, creativity and leadership to our squad. We are delighted to welcome a player of his influence and experience, both on the pitch and within the dressing room, as we continue to build a team ready to challenge for the biggest honours.”
