Brendan Rodgers has been in charge at Celtic for just over two weeks.
Rodgers has been in charge at the Bhoys for just over two weeks now, and he has been getting to know his new squad.
Armstrong claims that he is yet to have an in depth conversation with Rodgers, but what he has heard from the Northern Irish boss has been useful.
“We’ve not had a full-blown conversation yet but he’s spoken to me about a few things and given advice,” Armstrong said. “He tells me how he wants to play and that’s been useful.
“My versatility has maybe been a hindrance in the past when I have been asked to play somewhere else.”
Armstrong has featured in both of Celtic’s friendly matches so far, but it is unknown whether Rodgers sees the former Dundee United man as a regular starter.
Armstrong made 39 appearances for Celtic last season, but he is yet to secure a permanent place in their starting line-up.
Armstrong will have strong competition for a number of players next season, with the Bhoys currently well stocked with attacking midfielders.
Celtic have been unbeaten in their first two pre-season friendlies this season, with their next match set to take place on Wednesday evening.
Celtic’s first competitive match of the campaign comes later this month, in Champions League qualification.
