Lille are reportedly facing a fight to keep hold of star Kalou

Salomon Kalou in action for Lille in Ligue 1.

Lille are facing a fight to keep hold of Salomon Kalou this summer, Sky Sports understands.

Kalou has impressed for Lille this season and he has been inspirational in their bid to qualify for the UEFA Champions League.

The versatile forward has scored 14 goals and has five assists in Ligue 1 this season and his performances have not gone unnoticed across Europe.

Arsenal are long-term admirers of Kalou and they failed in a bid to sign him on loan during the January transfer window.

The Gunners are thought to be keeping tabs on Kalou’s situation, while Premier League rivals Liverpool are also tracking the former Chelsea man.

The likes of Roma, Atletico Madrid, Monaco and Galatasaray are all tracking Kalou as they look to bolster their attacking options next season.

Kalou, who has two years to run on his contract at Lille, is thought to be keen on a move back to the Premier League, but he will not make a decision on his future after the World Cup with Ivory Coast.
