Martinez’s side take a 2-1 lead into the second-leg of the last-16 tie in Ukraine, but they were unable to train on the Olympic Stadium surface on Wednesday, with the turf covered by protective sheeting.
They ended up working on a running track surrounding the playing surface, and Martinez admitted to being disappointed with the state of the pitch, although conceding it could adversely affect both teams.
“Dynamo Kiev are a technical team and they need a good pitch, and we are??exactly the same,” Martinez said.
“I don’t think it will play a big part in terms of giving a favour or??advantage to either of the two sides.
“I think it is a little bit of a shame for the game of football that the pitch??is not going to be in perfect condition.
“But you have to adapt to whatever surface you play on.”
