"I'm just looking for options to fall my way at the moment, so I'm training with Charlton to keep fit " he told BBC London 94.9
"I've definitely got a few more years in me," the Euell said after finding himself without a club for the first time in his playing career.
The Jamaica international played three Premier League games for Blackpool in the 2010/2011 season before a loan move to Doncaster saw him make a further 12 appearances in the Championship.
The ex-Wimbledon forward said he would consider dropping down a level again in order to secure a deal.
I've been busy on a mentoring programme in schools because you can't just sit back.
"I finished last season at Doncaster in the Championship and scored goals so I still feel I have a lot to offer at that level without a doubt.
"But I'm not going to be naive. You have to keep your options open and if the opportunity comes to me I'd be happy to take it, whatever league that would be," he said.
While former colleagues return to pre-season training, Euell has been mentoring and working towards his coaching badges.
"I've been busy on a mentoring programme in schools because you can't just sit back, get into a little box and hope for something to happen. You have to keep yourself busy," he said.
"Once pre-season starts up and down the country you don't want to be left behind, so that's why I gave Chris [Powell, Charlton manager] a call to see if he would let me come in and train, so I wouldn't miss that much pre-season when that call comes in," he said.
According to the Professional Footballers Association, 436 professional footballers found themselves out fo contract at the end of last season.
So, as well as calling his old teammate Powell, he has also spoken with his agent who is trying to arrange a deal.
"I sat and had the meeting with the agent, who then goes around and makes the calls to clubs up and down the country that could fit the bill for what I offer.
"It's one of those scenarios. You would like something to be done sooner rather than later, so you can go straight back into pre-season when that day comes around," he added.
