Romelu Lukaku was instructed to delete a controversial social media post revealing confidential details of Manchester United’s training statistics as the wantaway striker’s strained relations with manager Ole Gunnar Solskjaer took another turn for the worse.

Lukaku took to Twitter on Friday to issue a firm riposte to those who claim he lacks pace by revealing the results of a running test during the Perth leg of United’s pre-season tour last month.

It showed Lukaku was second only to Diogo Dalot (36.43km/hour) with a maximum speed of 36.25km/hour and charted the speeds of 22 other United team-mates. The tweet was accompanied with the words “lack of pace” next to laughing and runner emojis.

But Lukaku’s decision to divulge such information publicly was dimly received by Solskjaer and the Belgium striker was ordered to remove the post immediately.

It comes as Lukaku pins his hopes on a move to Juventus or Inter Milan this summer. United are in talks with Juventus about a potential swap-deal involving Paulo Dybala, although the Argentina striker is reluctant to leave the Italian club against his will and has reservations about a move to Old Trafford. Antonio Conte, the Inter coach, is eager to sign Lukaku but the Milan club - who had a £54m bid rejected last month - need to offload Mauro Icardi to be able to fund a deal.
