Brendan Rodgers has cast his verdict on Sebastian Tounekti's Celtic debut.
The winger got the nod on the left wing as his side secured a late win away at Kilmarnock.
Tounekti impressed with his display, continually looking to take on his man and make things happen.
"What a brilliant debut by him," Rodgers told Sky Sports post-match. "You could see in that first half, when he got the ball, he's a real danger and a real threat.
"He's fast, he's dynamic, he can beat a player, and he's a real Celtic winger.
"[In the] second half, we looked to feed the ball more into those wide areas."

Tounekti, signed for just over £5m from Hammarby on transfer deadline day, came off with the scoreline poised at 1-1.
Kelechi Iheanacho, also making his debut and green and white, then won it for Celtic from the spot in the dying embers.
A controversial awarding of a penalty, the SFA's full guidance for it has since been revealed: "The penalty [was] awarded for handball by the Kilmarnock defender whose arm was in an unnatural position," it read.
"Deflection does not always negate a handball offence. He doesn't know where the ball is going, and his arm is up in an unnatural position to block a shot."
Celtic moved nine points clear of city rivals Rangers with their victory this afternoon.
They sit at the top of the Scottish Premiership on goal difference, with Heart of Midlothian closely trailing them in second.
