Premier League giants Arsenal have no illusions about an easy ride in the Champions League.

Gunners boss Mikel Arteta was asked about what they expect when they face Lens in France on Tuesday.

Following an impressive home win over PSV Eindhoven in the first group stage game, Arteta believes they face almighty task to get a result in France.

“I was really impressed with what they did last year," he told reporters.

“It's incredible to finish in that position, and the way they did it, the form they had at home.

“This season they have been really unlucky with some results. I don't know how they don't have more points, so we expect a huge battle tomorrow.

“We are more than aware of it. They are a really good side and we have a huge test ahead of us tomorrow."
