Kolo Toure says Manchester City will be kicking themselves over letting him go to Liverpool after the 32 year old sealed a move to Merseyside in the most recent summer.
Toure was struggling for game time with City and was seen as a good replacement for the outgoing Jamie Carragher by Brendan Rodgers, who was on the lookout for a defender that could offer experience and guidance to younger players.
And as the Reds continue to fly in the Premier League, currently sitting in second position in the table and two spots above City, Toure says his old side are now fully aware of just how important he is to the squad in their mission to be successful.
"I was better than certain players at Manchester City but I was left on the bench," he told The Sun. "Before I left the club, I told the people in charge that they would regret letting me go.
"Now I am at Liverpool - and I am sure that City must be kicking themselves when they see how I am performing."
City are currently settling into life with a new manager in Manuel Pellegrini but have had some unpredictable results so far this season. But at the weekend their sheer might was shown with a 6-0 thrashing over Champions League-hopefuls Tottenham.
The side are also on the brink of qualification for the last 16 of the Champions League. Meanwhile, Liverpool, who missed out on European football all-together last season, have been able to concentrate fully on their league position and are aiming for a top four finish.
