The Frenchman drafted in Per Mertesacker, Mikel Arteta, Yossi Benayoun, Ju Young Park and Andre Santos in the final days of the transfer window to add quality and raise the average age of his first-team squad.
“Sometimes we are reproached for not having enough captains in our squad, now we have plenty,” Wenger told the Official Arsenal Magazine.
“Overall we have more experience and this could be important if we are in a strong position should we have interesting challenges in March or April. That could have a big part to play.
"We got criticised a lot last season for not getting over the line, but I believe that we were so close, so, so close that it was unbelievable to accept. But we have added more experience. Also last year we lost important players in March and April because we went for all the trophies, so hopefully we have the squad to do it and this time it will happen.
“In every position you always have number one, two and three, knowing there is a not a lot between them. But basically I’m very happy with the signings we made and my challenge now is to prove that I made the right decisions. I have great belief in the players I bought in and I am convinced they will prove me right.”
