3) Mario Mandzukic v Per Mertesacker
Mandzukic came off the bench after the hour mark for Bayern at the weekend, indicating that he’s likely to spearhead the side tonight ahead of Thomas Muller.
The Croatian is exceptional in the air, meaning 6 ft. 5″ Arsenal centre-back Mertesacker will likely be charged with marking Mandzukic in the box. If Arsenal are to have any chance of nicking an unlikely result, they probably have to keep a clean sheet, meaning Mertesacker will have to be at his very, very best.
