Nikola Vlasic has been blown away by Declan Rice since arriving at West Ham United in the summer.

The Croatian, signed from CSKA Moscow, has been stunned by the England midfielder's "unbelievable" quality.

Asked who had impressed him most since joining the club, Vlasic told reporters: "Probably Declan Rice.

"When I talked with my friends I knew he was a good player, but when I watched TV I thought: 'Okay, he is a defensive midfield player and maybe he is not that quick or fast, maybe that is a minus for him'.

"But he is so fast and so quick and even with the ball this season I think he is much better and improved in attack. He is unbelievable for me, he has impressed me the most."
