The state of the Luzhniki Stadium pitch is causing concern ahead of Wednesday's all-English Champions League final between Chelsea and Manchester United.

Englishman Matt Frost, who oversaw the laying of a new grass surface at the Moscow venue just 15 days ago, admits he has fears ahead of the game.

"The pitch is acceptable but it is a big personal disappointment for me,"

"Things didn't go well from the start, the pitch has only been down 15 days."

The old synthetic pitch was ripped up after England's Euro 2008 qualifer against Russia in October and a new grass one laid in readiness for the final.

But experts decided it was too bumpy, prompting stadium authorities to lay another at a cost of £160,000 and using turf from Slovakia.
