There are various thoughts on how many transfer windows it takes before you can judge a manager.
At the moment Brendan Rodgers is in the midst of his third window with barely a murmur of complaint as the squad looks forward confidently to a Champions League qualifying campaign with three domestic trophies in the boardroom.
Two years ago Rodgers’ predecessor Ronny Deila was at the same stage in his Celtic career but it was at this point that it all went wrong for the Norwegian.
There were real grounds for optimism at the time with only a horrendous decision from Steven McLean denying Celtic a likely treble.
During the January transfer window Gary Mackay-Steven and Stuart Armstrong were brought in with both making an instant impression while Europe had delivered a thrilling tie with Inter Milan to dampen out the memories of Maribor and Legia Warsaw.
A new contract had been set up for Kris Commons with the squad looking in good health even if Jason Denayer and John Guidetti had moved on.
Hopes were high for the transfer window but for a variety of reasons it all went badly wrong with a window of promise turning out to be the beginning of the end for Deila.
