The man that proved the architect of Manchester City's Champions League downfall will now work alongside them at the Etihad Stadium.
The Barcelona star opened the scoring at the Nou Camp as they booked their place in the quarter finals of Europe's premier club competition with a 4-1 aggregate win over Manuel Pellegrini's side.
But City are now hoping to benefit from the man responsible for developing Messi into the world-renowned player he is today after Rodolfo Borrell joined the ranks at the Etihad Stadium.
Borrell is widely recognised as the man that nurtured Messi's talents, as well as those of Cesc Fabregas and Gerard Pique, during his time as a coach at Barcelona's famed La Masia academy.
He has earned similar plaudits during his time managing Liverpool's youngsters between 2009 and 2013, after then manager Rafael Benitez drafted him to revolutionise the setup.
Under Borrell's tutelage, seven academy graduates went on to make their senior debuts for Liverpool last season while Raheem Sterling and Jon Flanagan, who both enjoyed lengthy spells in the club's under-18 ranks, have gone on to become first-team regulars.
But the 43-year-old was relieved of his duties at the club's Kirkby centre of operations last November, alongside academy director Frank McPartland.
As City's International Technical Director, Borrell will head up the senior football management team at the Etihad, alongside former Barca chiefs Ferran Soriano and Txiki Begiristain, and will also oversee their network of overseas clubs, which includes New York City FC, set to make their MLS debut in 2015, and Australian outfit Melbourne Heart.
