Celtic manager Neil Lennon has resigned after a calamitous defence of their Scottish Premiership title

Celtic manager Neil Lennon has resigned after a calamitous defence of their Scottish Premiership title, with fierce rival Rangers set to be crowned champions, the club said Wednesday.

A club statement said, “Celtic Football Club today announced that Neil Lennon has resigned from his position as football manager with immediate effect.

“Neil has served the club with distinction as both player and manager, delivering numerous successes, most recently completing the domestic treble in December.”

The 49-year-old said he had failed to turn around a difficult campaign and felt it was in the best interests of all parties he stepped down.

Celtic trail Rangers by 18 points in the Scottish Premiership.

“We have experienced a difficult season due to so many factors and, of course, it is very frustrating and disappointing that we have not been able to hit the same heights as we did previously,” Lennon said in a statement.
