Although he signed a new six-and-a-half year deal in November, it is reported that Hector Bellerin would consider joining Barcelona in the summer if Arsene Wenger were to leave, according to the Guardian.
Bellerin has been continually linked to Barcelona following the departure of Dani Alves with many Spanish news outlets concluding that Barcelona have identified Bellerin as their main target this summer. Barcelona have tried to convert Sergi Roberto into a right-back but have finally concluded that Roberto is not up to standard.
The Catalan club are willing to spend big money on the previous La Masia player. Like multiple players at Arsenal, Bellerin is incredibly loyal to Wenger, who was a major factor in him rejecting interest from Manchester City last summer. If Wenger were to leave, however, Bellerin would certainly question his future at the club, therefore inviting interest from other clubs.
