“I think it’s okay. And if no presidential candidate for Vasco appears at his house, I think that maybe he will come.”
Kalou started his professional career with Feyenoord before he then joined Chelsea after three seasons in the Eredivisie.
In England, he enjoyed a trophy-laden spell. He won the Champions League, one Premier League title, four FA Cups, a League Cup and the FA Community Shield.
On the international scene, he made his debut in 2007 and went on to score 28 times in 97 appearances for Ivory Coast since then.
