There is no end to Arsene Wenger’s Arsenal reign in sight even as he prepares for his 20th season at the club, CEO Ivan Gazidis has confirmed.

The Arsenal manager’s future looks to be brighter than it has been for several years, with a more expensively assembled squad that is confident it can compete with Chelsea for Wenger’s first league title in over a decade.

In early 2014, as his previous contract expired, there were numerous questions as to whether the manager's time at a club he has come to define should come to an end, with a growing section of Arsenal supporters calling for his head. However back-to-back FA Cup triumphs and a string of new signings have given both manager and club a new lease of life.

The 65-year-old has shown no interest in ending his 46-year footballing career, recently admitting that unlike Sir Alex Ferguson he has few outside interests to sustain him. With the support of the board Wenger could even overtake his former rival’s record of 27 years at the Old Trafford helm.

Gazidis told The Straits Times: "He's been incredibly important for us... You never know but he's in great health and he's doing incredibly well. He's full of energy and enthusiasm, his hunger is still there, and I'd never put an end date on it.

"He's also been a passionate supporter of the club, in a sense a fan of the club. He's put the club's progress and development above his own personal interest.

"We believe we have the right man in the club and we're very pleased that he's full of health and willing to carry us forward."

And Gazidis shares his manager’s confidence that the club are building a squad capable of challenging for the title.

He added: "We've got a growing sense of belief in our squad. We want to be more consistent going into next season... we definitely have the quality in our squad to compete and win the league."

That sense of belief has been supplemented by a series of big money moves in recent seasons, a dramatic volte-face from the club’s previous policy of relatively cheap, young imports. Spending £42.5 million on Mesut Ozil, £35 million on Alexis Sanchez and £11 million on a 33-year-old Petr Cech suggest a level of ambition to rival Real Madrid and Manchester United.

However Gazidis warned that Arsenal had spending limitations that their biggest rivals do not. Instead the CEO considers the club’s ability to develop youngsters along with big money recruits, in a way more reminiscent of Barcelona’s La Masia and Ajax’s youth academy.

"We're not able to compete at that level [with the likes of Real Madrid] yet,” he said. “It's true now we also have the ability to add some top players.

"But what's more important to us is that we're able to continue our (youth) development philosophy and then hold on to the players.

"That's the most exciting story, that's what the success of Arsenal is built on and is going to be built on. And if you look at all the most successful football clubs over time, they all have that at their heart."
