Tomas Kalas may finally be ready to call time on his Chelsea career.

The centre-back is currently on loan with Bristol City. It is the Czech's seventh loan spell away from Stamford Bridge.

Despite only signing a new Chelsea contract 18 months ago, Kalas says it might be time for a new beginning.

"I always wanted it [to play for Chelsea] but if I can see for myself the way it goes, or the way it went so far, and I'm not sure," Kalas explained.

"But obviously when Chelsea come with a new contract, as they did a year and a half ago, it's quite difficult to turn them down because you're not playing just for fun, it's your job and that's the perfect opportunity to have some security.

"People may look at it and say 'you signed for the money and could have gone somewhere for less money, where you could settle down', but I don't think you'd find a person who wouldn't have done the same thing.

"They deserve loyalty from me and I'm thankful that they brought me into big-time football and obviously as long as it makes sense, I'll keep loyal to them and keep faith that maybe one day I can become a first-team player – though obviously we have to be realistic and not live 'in the sky.'"
