Jack Wilshere starred as Arsenal romped to a 6-0 thrashing of BATE Borisov at a half-empty Emirates Stadium in their final Europa League group game on Thursday, while Marseille booked their place in the last 32.

Arsene Wenger made 11 changes to the team that were beaten by Manchester United at the weekend, but the Frenchman's second string put in promising displays to give him a 700th win as Arsenal manager.

After injury-plagued Mathieu Debuchy started the rout in the 11th minute by drilling home his first goal for 1,082 days and Theo Walcott tapped in, two minutes before the break Wilshere ended his Arsenal goal drought that dated back to the final day of the 2014-15 Premier League season.

A Denis Polyakov own goal made it four early in the second period, before Olivier Giroud scored his sixth goal this term from the penalty spot and Mohamed Elneny completed the rout with 16 minutes left.

"It's a bit of a relief [that I scored]. It's one of those games -- it didn't mean anything because we had topped the group," Wilshere told BT Sport. "It's one of those games you need to be in the right mind -- we enjoyed it. We're happy to go into the next round. All we can do when we get our opportunity is give the manager a headache."

Arsenal finished four points clear of Red Star Belgrade at the top of Group H, as the Serbs joined them in the knockout stage with 1-0 win over struggling Bundesliga outfit Cologne.

Cologne, still waiting for a first Bundesliga win of the season, only needed a draw in Serbia to qualify after beating Arsenal last time out, but a Slavoljub Srnic goal sent their season from bad to worse.
