Time to take a look at some players who have worn both Boro red and The Blues' blue.
Academy graduate Parnaby enjoyed a four-season stint at St Andrew's in between his two spells with Boro. The full-back made more than 60 appearances for Birmingham, some in the top flight but the bulk coming in the 2008/09 season as the club finished second in the Championship and returned to the top tier at the first attempt under Alex McLeish. Parnaby returned to Boro in 2012 before finishing his career with Hartlepool United. Parnaby’s Dad Dave was our long-serving former Academy Manager.
Queudrue was a fan favourite at the Riverside after arriving on these shores from Lens in 2001, becoming part of the Boro side that won the League Cup in 2004 and reached the Europa League final two years later. Having initially left Teesside for Fulham, a spell with Birmingham that followed wasn’t quite as smooth sailing for the French full-back, but he bounced back from initial struggles to be voted Player of the Year by Blues fans and local newspaper the Birmingham Mail for the 2007/08 season. He even earned a personal message of congratulations from owner David Sullivan, who had been one of his harshest critics in the early stages of his career in the Midlands. A loan move to Colchester followed for Queudrue before returning to Lens in 2010.
Striker Jutkiewicz counts Boro and Birmingham as two among a number of the clubs he has represented at this level. The former Coventry man left Boro in 2014, and went on to play for Lancashire duo Bolton and Burnley. Like his time on Teesside, Jutkiewicz’s spell with Birmingham began as a loan, a move which was later made permanent. He has since established himself as a fixture in The Blues line-up, and has played more than 100 games for them over the last two-and-a-half seasons. The 29 year old has scored 10 already this season, including a hat-trick against Rotherham United.
One of two former Blues players now at Boro, Shotton joined Birmingham on loan from Derby in the latter stages of the 2015/16 season. The switch became permanent over the summer, and Shotton was near enough a mainstay in the team at centre-back throughout the following campaign - making more appearances than any other Blues player. Shotts won fans over at St Andrew's after dying his dreadlocks blue for a match with Midlands rivals Aston Villa.
Birmingham was one of a number of destinations for Italian playmaker Fabbrini, who was a serial loanee during his time with Watford. He initially played for The Blues on a temporary basis in the 2014/15 season. The following year, he joined Boro on loan - but again it was short-lived. His time on Teesside would only last until January, at which point he was signed by Birmingham on a permanent deal, with Boro moving to replace him with Southampton's Gaston Ramirez. Fabbrini has since spent time on loan out from St Andrews with Spezia and Real Oviedo, before joining Romanian side Botoșani on a permanent basis last September.
Our other former Bluenose, Randolph spent two years at Birmingham having joined from Motherwell on a free transfer in 2013. The goalkeeper missed just one league game due to suspension over his two seasons there before moving on, again as a Bosman signing, to Premier League West Ham United.
A number of former Boro faces occupy the Blues dugout, including manager Garry Monk and coaching staff including James Beattie. The Teessiders also have an ex-Birmingham face in our backroom team. Irish defender Fleming followed a decade and over 250 appearances at Boro with a brief, six-game loan spell in the Second City in 2001 before moving to Crystal Palace.
