Arsenal hero Ray Parlour is convinced by the quality of Arsene Wenger's current team.
Parlour still believes his former club need two more top quality signings but claims Petr Cech can help take them to the next level in the Premier League this season.
Parlour told the Mirror: “It's definitely the best squad since the Invincibles. They need to steer clear of injuries. Last season, if the injury list was a bit lighter at certain times then they would have been a lot closer.
“The most important thing in any squad is to have the right team spirit and harmony. Everyone has to be pulling in the same direction. You can't have some not getting on with others, a personal feud or something like that.
"At the moment, it's the best I've seen in terms of team spirit for a long time. I think now, winning the two FA Cups, they believe they can go to the next level which, for me, is winning the league. That's the most important trophy. That shows you how consistent you are throughout the season."
