Bolton manager Owen Coyle would not be surprised if Arsenal mounted another bid to sign star defender Gary Cahill during the January transfer window.
Cahill was at the centre of some irritation between the Gunners and Saturday's opponents Bolton last month after lodging what Coyle felt was a 'derisory' bid for the England international.
And even though Cahill remained at Bolton, it is by no means certain he will stay at the Reebok for the rest of the season, with Coyle admitting: "I wouldn't be surprised if they came back."
"He added: Arsene has always said he is an admirer of Gary Cahill. But the clubs never agreed a fee."
"Gary has nothing to prove. He is a top performer, who is set for a glittering career."
After developing a personal relationship close enough for Coyle to secure the services of Jack Wilshere during the early part of 2010, it did appear the Cahill saga had caused some tension between the Bolton boss and Wenger.
Coyle insists that assessment is not true. And he is adamant there will be no friction between the dugouts on Saturday at a time when Wenger is under more pressure than he has ever experienced at Arsenal.
"The only tension will be that we both want to win the game," he said. "In fact, the criticism Arsene has received is absolutely ridiculous.
"He is one of the best managers in world football. Always has been. Always will be.
"The nature of the league we are in, with its global coverage, is that everybody has an opinion and sometimes there will be criticism."
