Lukas Jutkiewicz initially joined Blues on loan from Burnley in August 2016, but following a string of impressive performances the deal was made permanent in January 2017 for a fee of £1m.
Born, in Southampton, Jutkiewicz attended the Saints' Academy before joining Swindon Town, where he made his debut as a 17-year-old.
His performances for Swindon saw him earn a move to Everton, where he spent three seasons and several spells out on loan, before departing for Coventry City.
He enjoyed a successful spell with the Sky Blues, where he found the back of the net 18 times in 69 appearances, before moving north to link up with Middlesbrough.
In July 2014, Jutkiewicz joined newly promoted Premier League side Burnley for a reported fee of £2.25m. He missed a large proportion of the Claret's 2015/16 campaign after rupturing his cruciate ligament in August 2015.
