Arsenal star sends warning to Jurgen Klopp’s Liverpool

Arsenal will face a major test of their credentials with the visit of unbeaten Liverpool on Saturday having won 12 matches of the season under Unai Emery. Juergen Klopp's side, second in the league standings on goal difference behind Manchester City, have only dropped points against the champions and Chelsea in their opening 10 matches However, Arsenal captain Laurent Koscielny has warned Liverpool to prepare to face Mesut Ozil at a time when the playmaker is in “unstoppable” form. "His goal bailed us out before the break and then his pass for Hector [Bellerin] on our second goal is the best ball you will see all season. And he added an assist for Auba after a great dummy and understanding with Laca. "When Mesut is in this form he is unstoppable and makes us win. He has extraordinary qualities. There are not many players like him in the world right now capable of producing a pass like the one for Hector, beating four opposition players with just one ball." According to Koscielny, Ozil's performance against Leicester is one that will live long in the memory but he wants the playmaker to be focused on his next challenge. "His display on that night will stay in people's minds for a very long time," said the defender. "It is a case of 'I was there when Ozil had that performance against Leicester'. "However, he needs to be at this level as much as possible this season. Great players are the ones playing at their best the whole season." Koscielny is nearing to his first-team return after sustaining a serious injury in the semi-final of the Europa League against Atletico Madrid last season.
