Toprak: We can’t afford any mistakes

Leverkusen defender Omer Toprak is pessimistic about his side's chances of getting a result against Barcelona in the Champions League on Wednesday.

The Bundesliga outfit need a win against the defending champions at BayArena to progress to the knockout stages of the competition.

Leverkusen are in a tough run of form at present, having won just one of their last seven games in all competitions.

And Toprak knows his side face a tough task against the Catalans following their defeat to Hertha Berlin on the weekend.

"We have to analyse the game against Hertha and look at our mistakes," he told the club's official website.

"We cannot afford to make the same mistakes versus Barcelona.

"Obviously, we realise that we have a very small chance to progress but we want to make the most of that small chance."
