“The manager knows what he wants. There has been a lift for everyone in the place and I really like his style of working. It’s only early days now, but everyone is enjoying the atmosphere.”
“It’s nice to be back in with all the boys and the new manager, so it’s both exciting and difficult. We’ve had five weeks off, which is the longest I’ve had off for quite awhile, so we’re just adjusting back to football life.
“There’s no real way of preparing properly. You can do runs yourself, but, ultimately, it’s about rest. I’ve had a lot of that and after a tough 11 months that’s important.
“I’m just looking forward to starting afresh and picking up from where I left last season. It was a nice way to finish after an up and down campaign, so if I can continue those performances then I’ll be happy.”
Armstrong, who was bought along with Gary Mackay-Steven in a joint £2million deal by ex-boss Deila from Dundee United in January 2015, made 31 appearances last season, scoring four goals.
