Claudio Bravo's move from Barcelona to Manchester City to link up with Pep Guardiola looks a fairly smart piece of business on paper.
An experienced goalkeeper who has won La Liga, the Champions League and the Copa America will certainly strengthen Guardiola's claim for a Premier League title - even if it is at the expense of Joe Hart.
But from a Barcelona perspective, the move may come as somewhat of a surprise given what he has achieved at the Camp Nou already.
Luis Enrique has preferred rotating Bravo with Marc-Andre ter Stegen throughout his tenure and the relationship between Barca's keepers has always been slightly unclear.
However, with Bravo's switch to Man City now official, details of how the pair got on have been revealed.
The Chile international, who has made over 70 appearances for the Catalan giants, reportedly did not get along with his German counterpart.
Julio Rodriguez, a close friend and coach at Bravo's first club Colo Colo, has admitted the 33-year-old's strained relationship with Ter Stegen drove him out of the club.
As quoted by Spanish publication Sport, Rodriguez said: "We must be loyal and respectful and always and support the teammate that plays alongside you.
"The bad relationship between Bravo and Ter Stegen was another factor that ended bothering Barca and nicknamed me."
It is thought Bravo took particular exception to some of Ter Stegen's comments about becoming Luis Enrique's first choice.
It has also been reported that the younger of the two also visited the club's offices to issue an ultimatum about his future.
Rodriguez continued to disclose that Bravo was not prepared to play second fiddle to the German and was keen to move once he was made aware of Guardiola's interest.
"At this point in his career at 33-years-old he decided to succeed on all [domestic and European] fronts - no challenge is too great for them," he added.
"When Guardiola called he didn't think twice, it's something that goes beyond the money he will receive."
Despite Bravo's departure, Ter Stegen will not have it all his own way as Barcelona have already announced the Chilean's replacement.
Jasper Cillessen has joined from Dutch side Ajax but it isn't known yet if Enrique will stick to his rotation policy or elect Ter Stegen as his No.1.
