Chelsea defender Tomas Kalas 'to rejoin Middlesbrough on loan'

Chelsea defender Tomas Kalas will reportedly rejoin Middlesbrough on loan next season.

The young Czech Republic international will spend the entirety of the next campaign at the Riverside Stadium, according to Sky Sports News.

Kalas was loaned out to Boro last season and made 17 appearances for the Championship outfit as they narrowly missed out on promotion to the top flight.

Boro and Chelsea are said to be in the process of finalising the paperwork to bring Kalas back to the North-East.
