London's "Arsenal" will begin their UEFA Europa League round of 16 battle on Thursday, facing Piraeus' "Olympiacos". Victory in this tournament could be the only salvation for the "gunners" to return to the Champions League next season, as the prospects for Mikel Arteta's proteges in the Premier League are not very promising. Before the first match in Greece, "Arsenal" defender David Luiz said that his team can triumph in the Europa League. "I think we can win this tournament, but we must take it step by step. It won't be easy, because "Olympiacos" is a great team, which played really well against both "Bayern" and "Tottenham". I have played in this stadium many times and it has always been tough. It all depends on us. We must continue to improve our game and move forward," - D. Luiz said while speaking to journalists.
