Sanchez and Ozil are both out of contract at the end of the season and have been linked with exits next month to prevent them leaving for free in the summer.

Manchester City are keen on Sanchez whereas Manchester United are interested in Ozil.

However, Robson reckons the duo will want to stay put and see out their contract so that they could get a bumper deal at their new club from next season.

“The interesting thing is are they going to sell Alexis Sanchez? Are they going to sell Ozil?,” Robson said.

“I think both those players won’t want to go now. I think Arsenal have made a big mistake. 

“If they were going to sell them they should have sold them at the end of last season and then bought replacements for them. 

“If they try and get rid of them now they’re not going to get that much money for them and I don’t think the players will want to go. 

“Players can then get a massive contract elsewhere, there’s talk of Mesut Ozil going to Manchester United and wait until the end of the season to get that big contract and go and join Mourinho again as he did at Real Madrid. 

“So I think that’s an area where Arsenal have made a big mistake. 

“So I think they will wait until the end of the season.”
