It may appear Stephen Welsh has breezed into the Celtic team in recent weeks but it's been no stroll in the park for the defender.
The centre-back, 21, was drafted into Neil Lennon's backline for a derby showdown with Rangers in October before facing up to Zlatan Ibrahimovic and AC Milan just a few days later.
Before then, he'd only made one appearance - against Hamilton Accies.
Welsh has since featured against Lille home and away and looks to have nailed down a place in the side for the time being.
Ahead of the trip to Ross County on Sunday, where Celtic will look to make it six wins in a row, the former Hoops youth player recalled those early games as an education, in particular facing Ibrahimovic.
He said: "The experience was huge. Two massive games in the season (Rangers and AC Milan) although we didn't come out on top in them.
"Especially in the European games, the quality you come up against is world class.
"You look at Ibrahimovic, he is a brilliant player, he doesn't move a lot but the quality shines through in the end.
"So yes, playing in those games gives you a reality check. That's how good these players at European level are.
"But for the manager to put the trust in me to go and play in those games of that calibre was a big confidence boost for me.
"When you get brought into the team and you start winning, it is a big confidence boost, especially when we are keeping clean sheets.
"That's a good few we have got now and we are just trying to build on that in the coming games."
Welsh was back in the team for the win over the 1-0 win over Aberdeen on Wednesday after missing last week's victory over St Johnstone with an injury.
The centre-back was taken off on a stretcher in the previous game against St Mirren with an ankle injury, which proved to be less damaging than he first thought.
He said: "I probably thought I was going to miss more than just one game. I came out of it with not a lot of harm done.
"I was just happy to be back in within a few days.
"We are short of numbers anyway in my position, so to make myself available the other night was good and to be put back in gives me a lot of confidence as well."
After a 1-0 victory over Aberdeen on Wednesday night to keep the winning run going, Lennon wants to continue the good work in Dingwall.
He said: "We came off it against Aberdeen in terms of our quality and intensity to play but over the last month or so things have been looking a little bit better.
"It is important we go up to Ross County and keep or confidence going and keep the level of performance very high and take it one game at a time, that is all we are thinking about at the minute."
