Barcelona's transfer market will continue after a busy summer.

With La Liga starting this weekend, the team must register their new players and try to sign Chelsea's Marcos Alonso.

The Catalan club will aim for Hector Bellerin after missing out on Cesar Azpilicueta, writes Mundo Deportivo. Bellerin is trying to get his Arsenal contract canceled.

Bellerin was one of La Liga's greatest right backs last season with Real Betis and won the Copa del Rey.

Betis wanted to sign the right-back, but like Barcelona, they have financial concerns and can't.

Barcelona are his best option because they've long loved Bellerin's profile. Mundo Deportivo reports that Barcelona has been interested in Arsenal's Ozil for four years.

Bellerin left Barcelona's academy for Arsenal in 2011, although he may return.
