1) Damien Martinez V Aleksandar Mitrovic
22-year-old Martinez will be making only his third appearance for Arsenal on Wednesday night, the other two matches being in the League Cup. Looking to take advantage of that will be a younger but more experienced striker in Mitrovic. The 19-year-old Serb is one of the hottest properties in Europe after scoring sixteen goals last season, and five so far this time round. Liverpool were linked in the summer. He will be looking to take advantage of the Arsenal keeper’s inexperience in Brussels.
