Wenger expects teams like Aston Villa, Tottenham and Wigan to be joining the race for the title in the coming year’s.
He said: “For me the so-called ‘Big Four’ in England is about to change. It won’t last much longer.
“This year in the Premier League there have been changes which are, in reality, good for football values.
“Manchester United beat Sunderland only in the last minute and drew at Spurs, we were beaten by Stoke and Hull.
“That will continue until March when clubs have earned their safety for next season but won’t be fighting for European qualification. Then these clubs will let things go a little bit.
“But the technical level in our league has increased because players are being bought from all over the world and bringing new talent.
“The other day, for example, Wigan had Kevin Kilbane, Jason Koumas and Amr Zaki on the bench! This is impressive in my view.”
