Well, they did attract our leading (only

) regular goal scorer to the club and will almost triple their investment by selling him next summer if reports are to be believed.
They also attracted a talent so hot (at the time) that Barcelona would not sell him to us without a buy back clause.
And although it finished tits up, they did attract the most high profile, world superstar player we have had at the club in many a long day, beating the RS for his signature.
Errrrm, you do know that Barcalona have had a club policy for quite a whilst now of inserting a buy back clause in all younger players they sell, Bojan for example had one when they sold him, as does Traore at Villa, Fontas at Celta, Dos Santos at Villareal, Halilovic at Hamburg.
Last season they actually activated a buy back clause to take Suarez back from Villareal
Thats 7 players at the very minimum who left Barca at a young age in recent years that they included the clause in, it's the clubs policy and doesn't mean anything that Deulofeu had one.
Basically they have learnt the lesson of being burnt in the past and losing young players that subsequently they have had to pay huge transfers for to get back the club so just include it as a safeguard - Fabregas and Pique being the most notable two that its happened with.
means absolutely nothing about how Deulofeu was rated by them - it is just a financial cover for them in case a player develops late at abother club, and also it appeases the Barca fans as they know any academy lad that suddenly becomes class elsewhere can be borught back easily
