2) Edinson Cavani (Paris Saint-Germain)
A huge investment, but £55m could be money well spent on Paris Saint-Germain striker Edinson Cavani, who would make a real upgrade on the likes of Olivier Giroud and Danny Welbeck upfront for the Gunners. The Uruguayan is known to be unhappy in France and has been linked with Arsenal before, though Liverpool and Chelsea could also be in contention.
