Arsenal fans have become accustomed to seeing some of their biggest stars depart in the past decade.
Thierry Henry and Cesc Fabregas both fled to Barcelona, while Robin van Persie and Samir Nasri both sought - and won - a Premier League title at Manchester United and Manchester City respectively.
The Gunners have been in that precarious position for too long now. It’s one of the reasons why it’s been 12 years since they last won the title.
The arrivals of Mesut Ozil and Alexis Sanchez have helped maintain Arsenal’s status as one of England’s elite clubs but Arsene Wenger will know only too well that failure to win the title could lead to their exits.
And Ozil and Sanchez aren’t the only players who could leave in search of trophies.
Hector Bellerin has established himself as one of the game’s most promising players, drawing comparisons with - and even praise from - Brazil legend Cafu.
“Bellerin is much like me at 21,” the former AC Milan defender said in a Twitter Q&A. “He is very fast and very impressive!! Big big future!”
It’s no wonder, then, that Barcelona and Manchester City are reported to be interested in signing the Spaniard.
Bellerin left Barcelona’s La Masia academy to sign for the north London outfit in 2011 and he could follow in Fabregas’ footsteps by returning.
Wenger's difficult task
Meanwhile, Bellerin is the sort of defender Pep Guardiola would love to see marauding down the right side at the Etihad Stadium.
Barcelona have a place in Bellerin’s heart, presumably, while City have the money to make him very, very happy. Wenger will certainly do well to keep him at the Emirates.
The one thing in Arsenal’s favour is that Bellerin has three years remaining on his current contract. It means the Gunners have three years to convince Bellerin to renew, and one way they can help their case is by winning the Premier League.
Cazorla: Bellerin has great potential
Santi Cazorla, Bellerin’s teammate, thinks letting the 21-year-old leave would be a “mistake” on Arsenal’s part.
"It is clear that Hector is the right-back of the future," Cazorla told the IBTimes UK, per Goal.
"You could see in the victory over Swansea how good he is. He was all over the place and never stopped running.
“For Arsenal it would be a mistake to let him go. It is obvious that many teams want him. There has been talk about Manchester City and Barcelona.
“He is a player with great potential and I am sure he will also be a key part of the future of the Spanish national team."
