Uefa’s player eligibility rules must change, insists Arsene Wenger

The Gabon striker, a January arrival from Borussia Dortmund, is unavailable for the Gunners’ trip to face Swedish side Ostersund as his former club could come up against Arsenal in the latter rounds, having dropped into the competition after finishing third in their Champions League group.
Another January signing, Henrikh Mkhitaryan, can feature because, although he turned out four times for Manchester United in the Champions League this term, the Red Devils remain in Europe’s premier club tournament.
