Chelsea striker Michy Batshuayi joined Chelsea for £33m from Marseille last summer but managed just one start in the Premier League.
Despite his lack of game time, Batshuayi scored nine goals for Chelsea this season including the goal against West Brom that secured the Premier League title for Chelsea.
Diego Costa believes Batshuayi has what it takes to be successful at Chelsea.
“He’s a great player and has an impressive future ahead,” Costa told Het Nieuwsblad.
“The last match he has proven that he has quality and scoring ability.
“He’s a guy that will still take major steps.
“Hopefully he continues to grow and continues to keep his wits.
“He has all the qualities to stay here.”
