If the gunners don't qualify, things will get easier for Barcelona
Héctor Bellerín is one of Barcelona's targets this summer. The club want to improve the right-back position, currently guarded by two players that weren't used to play there: Sergi Roberto and Aleix Vidal. Bellerín also started as a winger, but he has been one of Europe's top right-backs for the past few seasons.
Arsenal are facing a very important match this weekend. They need to beat Everton at home and hope that Liverpool doesn't win against Middlesbrough at Anfield. If this happens Wenger's team will qualify for next season's Champions League. They also have the option of scoring a lot against Everton and expect Manchester City to lose against Watford, but this seems less likely.
Mundo Deportivo reports this Thursday that if Arsenal don't qualify for the Champions League, then things will get much easier for Barcelona when trying to sign Bellerin. Arsenal are looking for a 50 million euros fee that may be decreased if they don't reach the Champions League.
