Arsenal may reportedly have to part with Laurent Koscielny to snap up Atletico Madrid defender Jose Gimenez. The Gunners are eyeing three additions this summer - a goalkeeper, a central defender and a holding midfielder. A host of players are expected to depart at the end of the season, although skipper Koscielny is not expected to be one of them. Gimenez has been linked with both Manchester United and Liverpool in recent times but Arsenal are also keen, reports Gol Digital. And it is suggested Diego Simeone would only be willing to sanction his departure unless a replacement is found.
