Bhoys ready for Barca: Armstrong
Stuart Armstrong says Friday's hard-fought victory over Kilmarnock was crucial in maintaining momentum ahead of Celtic's return to Champions League duty this week.
The 24-year-old scored the only goal of the game just before the break at Rugby Park and, ahead of Wednesday's home clash with Barcelona, said: "I thought we were really good in the first half, moved the ball really well and created a few openings and we should have been more than one ahead. The second half was a bit ugly.
"We didn't control the game as we would have liked but it was a hard battle. We got three points and we got another clean sheet.
"We want to produce the performances we know we can week in, week out, but sometimes it's not going to be like that.
"Friday night was cold, it was on astroturf and a lot of the boys were just back from travelling away (on international duty). Three points were our objective and we managed to get them.
"We have an important week ahead of us with the Champions League and the League Cup final. We wanted to have good momentum with a win and now we can focus on next week."
And Armstrong is hopeful that his goalscoring exploits on Friday will earn him a place in Brendan Rodgers' XI against the Catalans.
He added: "Everyone wants to play in the Champions League and against the world's best players and we have a chance to redeem ourselves on Wednesday after the disappointing away game, so we are looking forward to that and we will make sure we prepare right."
