The former Chelsea striker, who plays with Ligue 1 outfit Lille, left Stamford Bridge at the end of last season.

Kalou and fellow Ivorian Didier Drogba both departed after winning the FA Cup and Champions League double - the latter heading to China, before finding himself at Turkish club Galatasaray.

The 27-year-old Kalou said he felt he achieved all he could in London and was left searching for a new challenge.

"My dream coming into Chelsea was coming into a big club and making history at the club," Kalou said.

"There was nothing better than that and I think we left at the right moment - that's when you win everything at a club like Chelsea - it's good to go and look for something else."

With Lille fifth in the French top flight and fighting for a Champions League spot, Kalou has enough on his mind.

But he admitted he still follows Chelsea's fortunes in the Premier League.

"I still follow Chelsea, I still follow them with a close eye," he said.

"I think they had a difficult start to the season but now they are back to the right place and they might win things again.

"They might win the UEFA Europa League and they are in the FA Cup semi-finals - so they might go for the double again."

Kalou also believes the quality of players in Ligue 1 is comparable with the English top flight.

With the likes of David Beckham and Zlatan Ibrahimovic plying their trade in France, he feels the league's reputation can only get better.

"Obviously the Premier League is one of the best but the French league wants to reach that level," he said.

"They want to bring in players with big names, they want to bring in quality players. And PSG's performance in the Champions League showed that. That's the right way to do it.

"If you want your league to be interesting you need to have players who can make that happen."

Kalou's Lille are at home to second-placed Marseille in Ligue 1 on Sunday.
