Former Celtic boss Brendan Rodgers eventually left Parkhead to join Leicester City.
Rodgers left Celtic to join Leicester back in February, and he has done a fine job since leaving Parkhead.
The 46-year-old has improved the Foxes considerably since taking over.
But Merson does not understand why Chelsea were not telling Rodgers to stick it out with Celtic until the end of the season.
The Sky Sports pundit claims that Rodgers could have been perfect for Chelsea, with Maurizio Sarri’s future still uncertain.
The former Arsenal midfielder said: “I don’t know how when Leicester went for Rodgers, someone at Chelsea didn’t go to Rodgers ‘just wait’.
“You’ve only got to look at what he’s done at Leicester in eight weeks. They’re passing Arsenal off the pitch. If they can’t buy anybody, he’d give people a chance.”
Rodgers may well have been forgiven for leaving by Celtic supporters if he had stuck it out until the end of the season with them.
The Northern Irish manager has taken on board a lot of criticism from the Parkhead crowd since leaving, as he decided to depart for Leicester just as their season was reaching crunch stage.
Celtic have still picked up some solid results since Rodgers left, and could well be on course to lift the treble for the third time running, with Neil Lennon now in charge.
