#1 Bojan Krkic
Bojan Krkic was hailed as a treasure by Frank Rijkaard and compared to Lionel Messi by a host of others. That had to happen, seeing how he broke the Argentinan's records as the youngest Barcelona player to make a debut with the first team and then scoring as well. However, little would have he expected his sailing ship to wreck in no time.
In the 2007-08 season under Frank Rijkaard, the youngster recorded 12 goals and 6 assists in 48 appearances. Those numbers are really impressive, considering he was just a 17-year-old and representing one of the giants in world football.
However, fortunes took a turn for the worse when Pep Guardiola replaced Frank Rijkaard as the steward of the club. Bojan displayed his reluctance in joining the Barca B team after getting a taste of first-team football. As a result, his relationship with Guardiola started deteriorating and the number of minutes he got to play dwindled as well.
Finally, the youngster left for Roma in 2011. He did return at the start of season 2013-14, but failed to make an impact and was loaned out to Ajax. Currently, he lies forgotten, serving a loan spell at Deportivo Alaves from Stoke City.
