Wenger signed a new two-year contract on Wednesday, prolonging his tenure at Emirates Stadium following their FA Cup win last weekend.

Arsenal have not won the league title since 2004 and Henry, who scored 228 goals for the Gunners, is hopeful his former boss can mount a challenge next season, after a fifth-place finish in 2016-17.

"I said two weeks ago he was going to stay and I wasn't wrong," Henry said. "People were talking to me about announcements today, but the announcement would have been if he was leaving.

"But he is not leaving, the board have assessed the situation to see if it was the best for the club. There is nothing new for me or at Arsenal. For 21 years - and now the 22nd and 23rd -- he will be here.

"As an Arsenal fan, and as a guy who had Arsene as a coach and have maximum respect for him, I'm happy to see him at the club. But time will tell [if the decision is correct

"They finished the season strong, although they have done that before. Raising yourself for the FA Cup final, to beat one team on one day is one thing. To do it over 38 games is a different story.

"Everyone is waiting for the title; the club, the players, the fans and Arsene himself.

"That's what I want to see because raising your game for one day is one thing, but everybody is waiting for that to be done over 38 games."

The former France international added: "I can only go with what Wenger is saying. He says the team is good enough.

"He might buy one or two players having, as he's claimed, created a dynamic to win the title finally. But I've heard that before, and the year before, and the year before.

"Hopefully a change in system might be the thing that helps them win the title next year."
