Arsenal have a mini-goalkeeping crisis on their hands this evening for their trip to Anderlecht, with the two frontline stoppers both out of action.
Wojciech Szczesny was sent off against Galatasaray in their last Champions League fixture so is suspended. On top of that David Ospina, a summer recruit from OCG Nice, is injured.
Which leaves Arsenal counting on 22-year-old Argentine Emiliano Martinez.
That is a fact that leaves many an Arsenal fan concerned. Because he did not exactly convince the last time he featured for Arsenal in a competitive match.
That was back in October of 2012, when he was in the starting XI for Arsenal against Reading in a League Cup tie.
He was not in top form as the Royals raced into a 4-0 lead against Arsenal, including this shot which he would have to admit, he should have saved.
In the end Reading scored five that day, meaning in two appearances for Arsenal Martinez has conceded six goals.
But while that is the bad news, here is the good news.
That game was almost two years ago and Martinez will be a far more developed stopper now. He has also played regular football whilst at Sheffield Wednesday on loan last season - so is more accustomed to British football than he was previously.
Thirdly, Arsenal scored seven that day. In fact, whenever Martinez plays it seems to rain goals for Arsenal. In two games in which Martinez has played for Arsenal they have scored a whopping 13 goals.
Maybe he is something of a good luck charm.
Arsenal fans will hope he brings those goals with him to Brussels.
