The biggest deal in history has finally been completed, as Manchester United have officially announced the signing of Paul Pogba.

The 23-year-old joins United on a five-year deal, with the transfer fee coming to a whopping £89m.

Pogba made 124 appearances for Juventus since joining the Italian giants from United in 2012, and scored 28 goals during his four year span.

The Frenchman was a key part of his country's run to the Euro 2016 final, and has been capped 38 times for the national team.

In a statement to the club's website, Pogba said it was the right time for him to go back to Manchester, and it excited for the season ahead.

“I am delighted to rejoin United,” Pogba said.

“It has always been a club with a special place in my heart and I am really looking forward to working with José Mourinho.

“I have thoroughly enjoyed my time at Juventus and have some fantastic memories of a great club with players that I count as friends.

“But I feel the time is right to go back to Old Trafford.

“I always enjoyed playing in front of the fans and can't wait to make my contribution to the team. This is the right club for me to achieve everything I hope to in the game.”

United coach Jose Mourinho was excited to land to superstar, and said Pogba will be an integral part of the United midfield for years to come.

“Paul is one of the best players in the world and will be a key part of the United team I want to build here for the future,” said Mourinho.

“He is quick, strong, scores goals and reads the game better than many players much older than he is. At 23, he has the chance to make that position his own here over many years.

“He is young and will continue to improve; he has the chance to be at the heart of this club for the next decade and beyond.”
