Real Madrid midfielder Toni Kroos says there'll be no underestimating Champions League opponents Atalanta.

The first-leg of the round of 16 tie will be held on Wednesday night.

Kroos said, “We have to do what we've done lately, which is push on despite missing several players. Those who are here must give their all.

“We always try to control the match and keep possession. We're facing a team that plays differently. It's going to be a complicated game, but we knew that already.

“Every game is like a Final, the Champions League starts now, but it won't be easy against a side that knows how to play football and attack. We will try to interpret the match in the best way, well aware we're going to have to defend too.

“You can win or lose a game based on how one sector of the team plays. If we build well from midfield, then we've got a good chance of getting a result.

“Our tactics don't always work, but we've been trying to improve them for years."
