The Sheffield United midfielder, who has been drafted into McLeish's squad ahead of the UEFA Nations League meeting with Israel at Hampden Park, met his new team mates for the first time following their return from Albania.

Logistical problems forced Fleck to miss the game in Shkoder but could win his first senior cap in a game which could see Scotland promoted to League B of the new competition.

"John trained today and looked extremely comfortable," said McLeish. "His composure on the ball was excellent. He's a very comfortable player and slotted in no problem."

Speaking after Scot's arrival at Oriam, Scotland's elite training centre, McLeish added: "Confidence is very high. I can tell, I can feel it, I can see it in the eyes. "We know that we have home advantage and a very good opportunity to do this. And these players can do this. It is a huge game for us.

"As I said, the players are showing the body language I would like to see from a team that is going into a very important game."
