Brendan Rodgers ran out of patience as he was once again quizzed on Celtic transfers after the win over Falkirk.
The Premier Sports Cup holders eased into the quarter-finals of this year's competition with goals from Daizen Maeda, Alistair Johnston, Dane Murray and a Liam Henderson own goal.
Rodgers has repeatedly been asked about the prospect of signing players in time for the Champions League play-off against Kairat Almaty and it was the case again last night.
His initial response in a BBC Scotland interview was: "I've just come out of the game here, so we'll wait and see. We've named the squad and then we'll wait and see what happens before the game. If not, that's the squad we'll go with."

When the interviewer tried to press for more, he bit back: "Okay, so let me repeat what I said. Right? I've just finished the game. I haven't spoken to anybody for the game and during the 90 odd minutes of the game, I don't know anything. I don't know anything. So, there might be, or there might not be. So, but we have the team that we have."
Murray, 22, had signed a new deal with Celtic earlier in the day and capped a brilliant day for himself by scoring his first goal for the club.
Rodgers was delighted for him and said: "He's a big talent. Fair play to Gavin (Strachan), he was working on that yesterday and getting the ball wide into that area to then go on the attack, you know, and he's he's very good in there.
"So I think it all comes from the delivery. The delivery onto his head was sensational, his speed, precision, and he got the rewards for that. But like you say, Ali's (Johnston) goal comes from the aggression, good numbers around the ball and then we can break away and and affect the goal."
Winger Yang was another who drew praise from the manager after having a strong impact off the bench.
But he wasn't the only one, with a number of fringe men seizing the opportunity to impress.
Rodgers added: "He (yang) did and he was very good. Came in and played with freedom, was excellent and that's what we want from movement was clever. Rolled inside when he had to and worked very hard. So, so yeah, overall really, really pleased.
"Again a lot of players who haven't played come in, they were there, giving great value to the team and like I say we had a really good variety in our attack tonight I thought. We crossed it, we made good runs, and yeah we were precise around the box when we had to be, but the variety in our play I thought was was excellent."
