Neil Lennon resigned from his post as the Celtic manager earlier today and former striker John Hartson has claimed that the Hoops need a proper rebuild of their squad in the summer.
There is no doubt that Celtic have regressed a lot over the past year and they are in need of quality reinforcements.
It will be interesting to see if the club hierarchy can back the new manager in the transfer market.
Celtic will need fresh investment if they want to compete with Rangers for the Scottish Premiership title next season.
