Pereira and Lukaku are now team-mates at Manchester United with both players set to play a key role this forthcoming campaign.

The former spent last season on loan in La Liga with Granada, impressing despite their relegation to the second tier of Spanish football.

Lukaku, meanwhile, is the club's marquee signing so far.

The Belgium international had been tipped to join Chelsea at the start of the summer but instead swapped Everton for Manchester United in a huge £75million deal.

And Pereira has given a glowing appraisal of the Red Devils' new No9, hailing his sense of humour.
