Arsenal have been linked with dozens of players this transfer window - from all corners of the world.
One of those earlier this summer was Argentine winger Eduardo Salvio of Benfica.
Portuguese newspaper A Bola claimed in late July that the international was likely to be the subject of an approach from Arsenal, having previously been linked with Manchester City.
Benfica, keen to keep him, said he could be bought - but only at a sky-high price of €40 million.
This seemingly ended interest from English clubs in the player - but there is bad news for the 23-year-old.
Salvio started the derby between Benfica and Sporting Lisbon on Saturday night, a game which finished a 1-1 draw.
However he played just 45 minutes, going down injured at the end of the first half clutching his knee.
It has been revealed this Monday that Salvio is suspected to have torn his cruciate knee ligaments, and could face six months out of action.
He is undergoing an MRI scan to assess the exact extent of the injury, but the signs are it does not look good.
It's disastrous news for Benfica, who will surely wish now they had lowered their asking price and cashed in on him.
