Wilshere didn't rate Manchester United's team as "the best we've seen".
He explained to The Sun: “Manchester United won the title last season yet it wasn’t the best United team we’ve seen.
“They won it because they had a big squad. If you look at their games, they sometimes rotated the whole back four.
“We’ve got a strong team at Arsenal and if we can add a few more to our squad then it can be a good season for us.
“We’ve got the Champions League, the FA and Capital One cups and the Premier League to contend with — it never stops."
