Shakhtar Donetsk winger Darijo Srna isn't surprised hearing Manchester United reviving their interest in teammate Douglas Costa.
Srna admits Costa is only likely to be a temporary team-mate.
"I've never seen such nimbleness - he is on a par with Messi. His speed with the ball and technique are out of this world.
"I know many scouts have watched him. Lots of clubs are taking an interest - the likes of United, Manchester City and Liverpool.
"He really does stand out, he makes a difference on the pitch. Douglas can beat three players with ease.
"This boy is hugely talented and is certainly a player destined for a big club."
