West Ham attacker Tomas Soucek says a quick start is imperative tonight against SC Freiburg.

The Hammers host Freiburg in the second-leg of their Europa League round of 16 tie trailing 1-0.

"We know we need to be on it from the get-go against Freiburg, and we can't afford to start like we did against Burnley," said Soucek. “We need to transfer how we finished on Sunday into how we start on Thursday.

“There was a big difference between how we played in the first half and the second half in our last game. We wasted lots of passes at the start and were poor on the ball, which was frustrating.

“I think we came back out after the break with the thought that we had to go for it and that we had nothing to lose, and we were a lot better. We know we just have to have the right mindset throughout the whole of the Freiburg game, because we're 1-0 down and chasing the game."
