Diego Costa not Chelsea's only threat, says Aogo

The 27-year-old is full of respect for the Premier League outfit and has made it clear Schalke's injury problems should not be an excuse

Schalke defender Dennis Aogo has warned that there is more to Chelsea than Diego Costa ahead of Wednesday's Champions League clash at Stamford Bridge.
The Spain international has been in sublime form in the opening weeks of the 2014-15 campaign, netting seven goals in four Premier League appearances, but Aogo believes Jose Mourinho boasts several world-class players to whom the Germans must play close attention.
"In Germany we have seen [Diego Costa] has had a great start to the season, but it's not just him," Aogo told reporters.
"The whole team is playing very well and they are not top of the Premier League for nothing.
"We are a playing against some of the best players in the world here so we don't need any extra motivation.
"Who is to say that we won't have a great day and compete at the highest level..."
Schalke are without a number of first-team regulars due to injury, but Aogo has insisted this should not be an excuse.
"Our captain [Benedikt Howedes] is missing, but we also have quite a few more players missing.
"Of course it is not easy but the players on the pitch have to stand up and compensate for that situation – and take responsibility. We can't just sit here and feel sorry for ourselves – we have to give our best on the pitch and try and make up for that."
