Chelsea have reportedly agreed a deal with Middlesbrough to loan them defensive duo Nathan Ake and Tomas Kalas for the entire 2015/16 campaign, according to the London Evening Standard.
Kalas, who is a Czech Republic international, has already been loaned out six times since his arrival in 2010, and spent the second half of last season on loan with Middlesbrough.
He is a central defender, who has made four appearances for the Blues so far and is still looked upon as a future first-team player.
Ake is highly rated by Jose Mourinho, and has already got a taste of first-team football at Stamford Bridge making 12 appearances so far.
The Dutch U21 international, who can either play at left-back or in midfield, will join his teammate in Aitor Karanka's side next campaign, as the Portuguese manager is keen to see if he can cope with the rigors of playing for a top championship side on a regular basis.
Chelsea and Middlesbrough have developed a good understanding. Apart from Kalas, Blues striker Patrick Bamford spent the entire 2014/15 campaign with the Riverside Stadium team, playing a key role in their run up to the play-off finals. They eventually fell to Norwich City, losing out on a promotion to the Premier League.
Another Chelsea youngster Charly Musonda Junior, who played a big role in Chelsea's Uefa Youth Cup campaign, is also looking to leave the club on a temporary basis, with the report claiming that a loan deal with Marseille is close.
According to another report in the London Evening Standard, Manchester City and Arsenal are keen on signing the youngster on a permanent basis. However, the Premier League champions are not interested in letting the Belgian midfielder, who is contracted until the summer of 2019, leave the club to join their direct rivals.
