Paul Pogba has failed to deliver his only Man Utd promise made when signing for the club

Paul Pogba is set to leave Manchester United at the end of the season, having failed to deliver his only promise when he returned to Old Trafford almost six years ago.

Once the January transfer window slams shut next Monday, the 28-year-old will enter the final five months of the contract he signed back in 2016 with the jury still out on his United career.

Pogba's long-awaited homecoming transfer commanded a world-record fee, as Juventus received £89million for the superstar they poached from United as a teenager.

Over the four campaigns between his two spells in Manchester, the club had to watch Pogba blossom into one of the world's best midfielders and begin an illustrious career, and the Frenchman came back promising the sort of titles he got his hands on in Turin.

"The thing with me is I only think about the pitch. I want to do great, I want to be one of the best, I want to win titles," a beaming Pogba stated with intent in his first interview on MUTV.

"I want to achieve things and that's all, that's why I came here, just to do this, to become one of the best and to win titles because I know this club has to win titles.

"I just focus on this and that's it. I'm just ready to go and work on that and just kill it."

Fast forward five-and-a-half years and the only two winners' medals Pogba boasts are for the League Cup and Europa League - not exactly what supporters wanted after that interview.

Of course, the France international was never going to do it alone but the quality he demonstrated while driving his nation to a World Cup win in 2018 left fans pondering just why Pogba looked a different player for the Red Devils.
