Chelsea outcast Diego Costa insists he holds no grudge against Spain teammate Alvaro Morata.

The former Real Madrid striker has joined Chelsea as a replacement for Costa.

But Costa told the Daily Mail: "Alvaro Morata is a great player.

"He had a big season in Madrid and at the sight of this completely crazy mercado, I really think they have this young and talented striker at a good price.

"He will triumph at Chelsea."

Morata scored on his Premier League debut in defeat to Burnley on Sunday.
