Cyrus Christie is poised to join Garry Monk's Middlesbrough

Cyrus Christie has completed a move to Middlesbrough after the club agreed a deal to sign the 24-year-old defender from Derby for an undisclosed fee.

Christie joins Norwich City's attacking midfielder Jonny Howson in arriving at Rockliffe Park, as new Boro manager Garry Monk completed a double transfer swoop on Friday with his first signings since taking over from Aitor Karanka last month.

Christie spent three years at Derby after joining from Coventry in July 2014, featuring 107 times for the Rams and scoring two goals.

Eligible to represent the Republic of Ireland through his Dublin-born grandmother, Christie has made 10 international appearances, scoring his first goal for Martin O'Neill's side during a 4-0 win over Gibraltar in September 2015.

He was awarded Derby's Young Player of the Year award in the 2015/16 season, as the team ended their campaign with a play-off finish.

Christie was sidelined last November after breaking a bone in his foot during a win over Wolves but returned to action in January.

He will join up with Monk's squad for the first time on Sunday to travel to Portugal for a warm-weather training camp.
