Andy Farrell admits having concerns about the Murrayfield pitch hosting this weekend's Calcutta Cup clash between England and Scotland.
Farrell, England's backs coach, thinks the Edinburgh playing-surface could resemble a mud bath by the time the teams take to the field on Saturday.
The ground is already looking worse for wear, with more heavy rain forecast overnight.
Both teams lost their opening Six Nations fixtures last weekend and will be desperate to get a win under their belts in game number two.
And Farrell said: "We knew it wouldn't be the best. It was cutting up a little bit while we were training.
"Who knows what will happen? It could teem it down and the pitch would be very bad anyway.
"It's the same for both sides. We're ready for any type of game."
He also said England are in great shape to bounce back from the heartbreaking defeat in Paris, where they lost 26-24 to France.
He added: "We want to build on what we started against France. The boys are pretty excited about this one.
"We played at a hectic pace in Paris. We were the aggressors of that and the ones pushing the pace. It was the most hectic game of the opening round.
"The players are excited about that and that's the standard we want to repeat.
"Now we need to tidy up a few bits of detail where we can get better and put that into consideration."
