Chelsea defender Tomas Kalas has admitted that he is excited about being part of the first-team squad at the Blues this summer.

The 20-year-old signed for Jose Mourinho's side in 2011 but spent the last two seasons on loan at Vitesse Arnhem.

Kalas told the club's official website: "Being part of the squad at Chelsea is what I was hoping for when I signed for the club. I didn't know that it would come so early, and that is why I went on loan to Vitesse to improve myself.

"I didn't expect that after two years I would be part of the first team squad but especially now it is exciting because how many players from my country at 20 years old can say they have played 63 games in the Eredivisie, and they can be part of the main squad at Chelsea?"

Kalas made 34 appearances last season for Arnhem in the Eredivisie.
