Reaction from Mikel Arteta at the Karaiskakis Stadium in Piraeus on Thursday after his Arsenal side struck twice late in the game to earn a 3-1 win at Olympiacos and take control of their Europa League round of 16 tie. However, the 'Gunners' almost proved architects of their own downfall once again. Martin Odegaard's first Arsenal goal put the visitors in front, but another defensive calamity gifted Youssef El-Arabi an equaliser just before the hour. Arsenal were rocked but recovered well and two goals in six minutes from Gabriel Magalhaes and substitute Mohamed Elneny earned a deserved victory. Arteta saw his side dumped out by Olympiacos in the round of 32 last season despite winning the opening leg in Greece - he will be hoping lightning does not strike twice.
