Arsenal legend Thierry Henry has claimed that the rotation of attacking stars will be vital to the club's success this season.

The Gunners smashed their club-record transfer fee to sign Alexandre Lacazette for £52m from Lyon this summer.

The Frenchman joins Olivier Giroud, Danny Welbeck and Alexis Sanchez as attacking options, while Theo Walcott could also fight for a place in the lineup.

The Gunners scored 77 goals in the top flight last year, nine fewer than North London rivals Tottenham Hotspur, while Sanchez ended the campaign as the club's top scorer with 24 league strikes.

"[Lacazette] has a different game to Giroud, which I think is good because you need different types of strikers," Henry told Sky Sports News.

"It's ironic when you think about it that Giroud starts for France and Lacazette is his sub, and it looks at club level like Giroud will be the sub. I don't know if that's ever happened in the history of the game!

"He did it in the French league and people might say it's a different league but, with due respect to Lyon, he'll also be with better players. I'm backing him to have a good season, but that rotation will be key.

"Sometimes you'll need Giroud or even Sanchez in the middle and sometimes you'll need Welbeck or Walcott, whoever will have an impact."

Lacazette scored 28 league goals for Lyon last season.
