It’s my problem and my job and I will solve this problem."If we want to play in the Champions League we have to play better."We have to run and fight. It’s not enough to just pass. Champions League is another situation - different from the championship.City failed to progress to the knock-out phase last season after collecting just a point from their opening two group matches.They now face a double header with Ajax before a home game against Real Madrid and a trip to Dortmund.
