Diego Costa has backed fellow Chelsea striker Michy Batshuayi to succeed at the club, insisting the Belgian has proved in recent weeks just how good of a goalscorer he is, reports the London Evening Standard.
Chelsea signed Batshuayi from Marseille in a £33million deal last summer and was brought on late in the club's match away to West Brom where he went on to score the goal that won the Premier League title for the Blues.
He followed up his title-clinching strike with another against Watford and then two in the 5-1 thrashing of Sunderland on the final day of the season, which Costa believes has proved just how much Batshuayi has to offer Chelsea in the coming seasons.
Costa, whose own future at Chelsea remains uncertain, said: "He is a big player and has an impressive future for himself.
"The past matches have proven that he has quality and scoring ability.
"He is a boy who will take great steps. Hopefully he will continue to grow - he has all the qualities to stay here.
"Batshuayi may stay because he's young and I could be leaving."
