The Celtic winger made just his second start for the club last week.
Morgan had a difficult debut season at the Hoops last term, making just one start under Brendan Rodgers and eventually being shipped out on a development loan to Sunderland in English League One.
Finding it difficult to make a big impact at the Stadium of Light too, there had been questions marks about his Celtic future heading into the summer.
However, involved in pre-season and impressing off the bench in the European first leg against Sarajevo, the winger was given a starting opportunity last week against the Bosnians at Celtic Park.
Now Lennon has revealed he's been encouraged by the player's recent progress too.
Speaking on the club's official YouTube channel, the Hoops boss said: "He’s started off very well.
"It’s my first time working with Lewis over a concerted period of time and he’s had a very good pre-season.
"He played very well in the two games against Sarajevo so he’s done his chances no harm at all."
With Mikey Johnston returning into contention after an injury problem, it'll be interesting to see whether Morgan can retain his place in the team against Estonian champions Nomme Kalju on Wednesday night.
The signs are good he could get plenty of action over the coming season and if he can continue to contribute assists and score a few goals, he'll embed himself firmly into Lennon's plans.
With pace, a direct nature and an eye for a cross, he could be a very effective weapon for the Hoops if he gets a run in the team and finds even more confidence.
