Stewart Downing told to stick around at Boro until right for everybody can be sealed

The 32-year-old has been unhappy at his lack of action in recent weeks and is understood to be looking for a loan move away from the Riverside Stadium during the January transfer window, with Crystal Palace leading the queue.

Karanka insists Downing remains part of his plans, having signed a four-year deal when he returned to his hometown club from West Ham during the summer of 2015, but admits he could go if the arrangement suits Middlesbrough.

The Spaniard said: “I have said always that (if) a player who wants to leave and Middlesbrough Football Club and another club agree the transfer...

“To find or to sell a player, to buy a player, to sign a player on loan, to bring in a player on loan from other places, all parties have to agree. If Stewart wants to leave and the clubs agree and everybody’s happy, then yes”

Karanka’s assertion that Downing has a future on Teesside has thrown the ball into Downing’s court, although it remains to be seen how keen Boro are to hold on to the player.

The midfielder prospered under Sam Allardyce at West Ham and the chance to work with him again in his new role as Palace boss could well prove attractive, although whether the Teessiders would sanction a switch to a direct rival in the battle for Premier League survival remains to be seen.

Downing doesn’t favour a return to the Championship where several clubs are monitoring his situation.

Asked about possible destinations, Karanka said: “If the club thinks that it’s good for the club, good for the player and good for the club, I can’t say anything.”
