Once again crowned champions of Scotland, but not goings unbeaten, it was business as usual at Celtic Park last season.
The Glasgow side also won the treble, winning the Scottish League Cup and Scottish Cup. In truth, this is something Celtic fans have come to expect.
The only negative to last season was crashing out of the Champions League once again. Brendan Rodgers must seek to improve his side in European competitions. Indeed, Celtic will be looking to once again exert dominance over their cross-city rivals Rangers, who have employed Liverpool Legend Steven Gerrard as boss
With that in mind, here are two Hoops players who need to impress Brendan Rodgers in pre-season…
Now 30 years of age, and playing a bit-part role in last seasons League campaign, Hayes will need to fight hard in pre-season to impress the Northern Irish manager.
One of the most exciting wingers in Scotland during his time with Aberdeen, rediscovering his form from his days at the Dons in pre-season would do wonders for Hayes.
A prolific forward in Scotland in the past, but Griffiths will have to prove he has still got it to Rodgers. Nine goals in 22 appearances last season was not a fantastic return by his standards.
When Rodgers has Odsonne Edouard and Moussa Dembele at his disposal, Griffiths is going to have to really prove himself in pre-season to get close to the starting eleven.
