For Arsenal manager, Unai Emery, this is a trodden path; he is not only one of the most successful managers in the Europa League, he has also been to France, where he handled Paris Saint Germain and he will have a few ideas on how to tackle Rennes, who in the Round of 16 saw off Spanish side Real Betis. Arsenal lost their opening leg in the Round of 16, away to BATE Borisov before recovering at home and starting away against a comparatively stronger side, The Gunners will have to put their best foot forward. Arsenal have lost just four of their 23 Europa League matches and while they have managed seven wins in their last 11 away matches in the competition, it is their away form that will worry their fans more, having picked just two wins in their last 10 away matches across all competitions. They have two losses in the last five away matches in the Europa League but have also picked a three comfortable wins in the process, twice scoring three goals. Rennes scored six goals in the two clashes in the last round as they bundled out Real Betis, but they conceded four across the two legs and this is an aspect that they will be out to prevent against Arsenal. Rennes are unbeaten in 12 home matches across all competitions. In 13 home matches in the Europa League, Rennes have lost just once.
