Speculation is growing over the lack of action Barcelona whiz Bojan Krkic has seen this season. Barcelona sources say the continued omission of Krkic from coach Pep Guardiola's first team is "worrying", particularly with the attack struggling for goals in the opening weeks of the new campaign.

Marca says a rift could be developing between the pair stemming from their days together with Barcelona B (now Barca Atleti) at the start of last season. It's understood Guardiola didn't take well Krkic's declaration that he wouldn't return to Barca B after the U17 World Championships.

Krkic has only just signed a new five-year contract - worth more than eight times his previous deal - but remains a periphery figure in Guardiola's plans.
