The 36-year-old is currently completing his coaching badges but wants to finish his playing career in the SSE Airtricity League.

Duff would be a huge addition to any squad and the Dubliner admitted that his own mother was asking questions about his appearance last weekend.

“My ma was upset, she thought I was signing for Pats and I hadn’t told her. We were obviously analyzing the game.”

The former Chelsea and Blackburn star is looking forward to getting back playing football, but has an open mind about his next club.

“I just want to play football and hopefully, touch wood, get fit and get back on the pitch.”

The Ballyboden native admitted that he is finding the FAI course very challenging and one of the most difficult things he has ever done.

“It is very tough to be brutally honest; it is probably the hardest thing I’ve ever done in my life.

“I’ve played against Messi at the Nou Camp, Ronaldo and it was easy playing against them compared to what we have been through this week.

“I have zero qualifications in life except for football, so I guess I’m not really interested in any other things but football. It was the next step really.”
