Sevilla midfielder Renato believes Arsenal are too shot-shy to be a Champions League threat.

The cocky Brazilian said: "Arsenal have a reputation for not scoring as many goals as they should because they often try to walk the ball into the net. They always try to dribble past one more rival or make one more pass. I watched them against Manchester City and felt that.

"They create a lot but have some difficulties scoring. I hope it is the same against us. We were lucky to be drawn in a group with Arsenal. Theoretically there were stronger rivals, like Chelsea and Milan.

"The games against Arsenal will be very tough but it is undeniable we are in a weaker group than some. I think we can fight for first position."
