Chelsea defender Tomas Kalas is keen to sign permanently with Middlesbrough.

However, the defender has made only two starts for the Blues since arriving from Sigma Olomouc in January 2011, compared with the 47 appearances he has made for Boro.

Kalas told the Evening Gazette: "I don't know how many games I've played since I came - probably around 40, which is not bad in one and a half years.

"That's why I came here, to play games and hopefully I'll keep playing next season - maybe here.

"If I could get the deal [to move to Boro permanently], I would really think about it. Yes, why not?"
