Chelsea defender Tomas Kalas could leave the club on a permanent basis according to agent Mithat Halis.
The Czech was loaned out to Sigma Olomouc, Vitesse Arnhem, FC Koln and Middlesbrough in recent seasons.
And he is ready to accept a permanent move to the Riverside since he would struggle to secure a regular place in new manager Antonio Conte's side at Chelsea.
"Kalas wants to stay in England next season, preferably in the Premier League," he said.
"He is happy at Chelsea but Middlesbrough are interested."
At the end of last season, the 23-year-old confessed that staying at Boro was a possibility.
"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," he said.
"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!"
