That has frustrated the club’s fans, who have had to watch the likes of Manchester United and Manchester City both strengthening with big money purchases.

They report that the Gunners had planned to cap their summer spending at £100 million, but instead have accepted they may have to spend more than another £70 million to get the men their side needs.
