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.
