Marseille midfielder Mario Lemina has no doubts that Arsenal are the best team in Group F of the Champions League.

The Gunners moved three points clear at the head of the table on Tuesday night thanks to a 2-0 win over the French outfit at the Emirates Stadium, which left their opponents still awaiting their first point of the campaign.

"We were playing against a very good Arsenal team who I think are the best team in the group," Lemina told the media. "We are disappointed because we wanted to get something, but they were stronger than us and they showed it from the beginning to the end.

"The coach said he will bring the young players into the side to give us a bit more experience. We also want to avoid the zero [finishing on no points] as it is humiliating in a competition like the Champions League."

Arsenal must avoid losing by three goals at Napoli in a fortnight to progress to the last 16 of the competition, while Marseille can no longer qualify for the Europa League.
