Chelsea youngster Tomas Kalas has revealed he's rejected an offer from Arsenal.

The 19 year-old Czech Republic defender is on-loan at Vitesse Arnhem this season.

He told Voetbal International: "Chelsea were always open and honest with me.

"Arsenal and Hoffenheim also tried for me, promising I would play in their first team. All the while, at Arsenal, they were signing Sebastien Squillaci and Laurent Koscielny."
