Rather than training on the pitch at their opponents' stadium as they normally would, Martinez's men did a session on the running track surrounding the playing surface - while the turf was covered by a protective sheet - following their arrival in Ukraine on Wednesday.
And when asked about the state of the grass, the Spaniard said at his pre-match press conference: "The pitch is a concern for both teams.
"Dynamo Kiev are a technical team and they need a good pitch, and we are exactly the same.
"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."
