Adidas have stepped up their marketing campaign behind Paul Pogba's £100m move to Manchester United. The Premier League giants are now on the brink of sealing a world record transfer to bring the Juventus midfielder back to Old Trafford four years on from his departure.

According to Italian newspaper La Stampa, Pogba's return to United will be announced imminently having undergone a medical in Los Angeles today (29 July) with negotiations over the fee paid to his agent Mino Raiola – thought to have been a major stumbling block – nearing its conclusion.

Adidas have now teased fans with their latest promotion video, starring two of their biggest clients in Pogba and grime star Stormzy, with all signs suggesting a deal is done.

"Don't believes everything you read in the papers," Pogba says in the video which then cuts to a shot of a United billboard with the words "blah blah blah" written across it – a clear reference to a tweet made by Raiola in reference to mounting speculation over the transfer.

The video then cuts to Stormzy, dressed in a United tracksuit stood outside Old Trafford, who quotes his 2015 single "Shut Up" after reading the United billboard, before the cameras cuts back to Pogba laughing.

Adidas, who signed a £750m deal with United in 2014, are unlikely to be in the business of trolling one of their biggest partners, suggesting something more official could be just around the corner.

Pogba himself contributed to the frenzied speculation – intentionally or not – with an Instagram post this week when he posted a black and white picture of himself from the United States, with the only colour provided by the midfielder's cap and shoes in United red.

United are expected to pay a new world record fee for their former player, eclipsing the £86m deal that saw Gareth Bale join Real Madrid from Tottenham Hotspur in 2013.

The club have already made three signings this summer in the shape of Eric Bailly, Zlatan Ibrahimovic and Henrikh Mkhitaryan, but Mourinho wants a fourth player before the window shuts on 31 August.
