Manchester United cult hero Diego Forlan believes the Reds' attacking threat could be an avenue that they can exploit against Atletico Madrid.
The Uruguayan's two former clubs go head-to-head tonight (Wednesday) in the first leg of their Champions League last 16 clash.
It will be just the third time the two teams have faced off but both have had similar disappointing league campaigns, and Forlan believes United can trouble Diego Simeone's side.
