Veteran defender Kolo Toure admits his biggest regret in an impressive playing career is not winning a trophy while at Liverpool.
The 36-year-old is part of an elite group of players who won Premier League titles with different clubs - Arsenal and Manchester City - while adding the Scottish Premiership crown to his list of achievements after a solitary unbeaten campaign at Parkhead.
Last season at Celtic also saw him become a double 'Invincible', repeating the feat from 2003-04 with Arsenal, but despite some notable near misses three trophyless seasons at Anfield still bothers the former Ivory Coast international.
Toure was released by Celtic this summer and with the offer of a potential player-coach role not yet forthcoming from the club the free agent still has hopes of extending his playing career.
He has spent most of the summer in Ivory Coast training and coaching within the national team set up and feels he can still do a job for a club.
While playing time was limited in the second half of the season Toure insists he still felt part of Celtic's unbeaten campaign for his second 'Invincible' achievement.
Toure admits offers of a playing contract may be scarce and has been considering what he would do post-retirement for some time.
Having worked under some big-name managers - Arsene Wenger, Roberto Mancini, Jurgen Klopp and Brendan Rodgers - he has a good knowledge base to tap into should he need advice on making the move into coaching.
