Rodgers succeeded Ronny Deila this summer following the Norwegian’s decision to step down as Hoops boss at the end of last season, prompting plenty of excitement around Celtic Park.
The former Liverpool manager is renowned for player development and advanced coaching on the training pitch, and it appears he has immediately made an impact in his short time in Glasgow.
Speaking to reporters, McGregor says Rodgers’ arrival has added fresh impetus while suggesting the bar has been raised in terms of quality as everyone is keen to impress.
“People want to impress. He has brought a fresh impetus to the squad. When a new manager comes through the door it gives everybody a lift,” McGrefor explained to Herald Scotland.
“We are all trying to do well and to impress to show we should be in the team. People say it has gone up a level but it has probably gone up another level beyond that again with people trying to impress.
“It can only be good because our sessions have been good, we are getting fit and working hard.”
Celtic have a large number of players on their books, therefore competition for places will be extremely tough which should then motivate players to impress further on the training ground.
The Hoops have been relatively quiet in the transfer market, and it seems Rodgers wants to take a good look at his new squad before making any big decisions on potential departures or new additions.
The Scottish Premiership champions so far have played two pre-season friendlies, with their latest being a 1-0 win over Sturm Graz.
