UEFA admit they are "slightly worried" about the appearance of the pitch for the final but they do not believe it will hamper the players.

The grass surface at Moscow's Luzhniki Stadium has come under scrutiny after groundsman Matt Frost said it had not had time to bed down following its laying just 15 days ago.

A second pitch was required after the initial one, placed on top of the 'plastic' surface normally used at the stadium, was deemed unacceptable.

UEFA officials are happy that the pitch will be playable, but spokesman William Gaillard said: "We are slightly worried about the look of it.

"In terms of the quality, we have made some tests in the last few days and it is fine. It may not look very, very green on television, but, essentially, it is a good pitch to play football on."
