Cavani finalises Manchester United move

The Premier League club have said the Ivorian will join the club "at a later date, subject to medical, personal terms and work permit".

In a statement on their official website, the club also said they had been tracking Diallo since 2016 when he was spotted playing at Under-15 level. 

Diallo featured three times for the Italian club's first team last season, scoring on his debut in a 7-1 rout of Udinese in October. 

United has not revealed how much the deal is worth but reports suggest it is in the region of £37million. 

United had a busy transfer deadline day, bringing in Edinson Cavani on a free transfer and Alex Telles from Porto, while Chris Smalling made a permanent move to Serie A side Roma.
