Manchester City boss Roberto Mancini is aware of Borussia Dortmund stars Robert Lewandowski and Mario Gotze ahead of tonight's Champions League clash.

Both players have been linked with City in the past.

"Borussia Dortmund have beaten Bayern Munich for the last two years," said Mancini.

"For this reason I think it will be a very difficult game. In my opinion Dortmund are one of the best teams in Europe. They won the Bundesliga. They are very strong and in players like Robert Lewandowski and Mario Gotze they are dangerous going forward. If we concede space, like we did in Madrid, we will make it difficult for ourselves."
