Nicolas Kuhn says Celtic still have room for improvement despite their 6-0 thrashing of Aberdeen – Scotland’s other form side – to reach the League Cup final.
The 24-year-old winger scored the fifth goal at Hampden to set up a meeting with either Motherwell or holders Rangers.
“I think, if you win 6-0, you don’t have to play better, but of course there are things to improve and we are going to do that,” Kuhn told BBC Scotland.
The victory ended Aberdeen’s 16-game unbeaten run since manager Jimmy Thelin arrived this summer while extending Celtic’s own unbeaten domestic run to 13.
The Dons are the only Scottish side to deny Celtic a win after coming from two goals down to draw 2-2 in Glasgow last month.
Asked if that Premiership match was in his side’s minds, Kuhn replied: “Not too much, but we all knew we had to do better and today was the cup and the goal was to get into the final.
“We learned our lesson from the league game against them and today we scored some good goals.”
The German was not concerned about the result sending a message to their league rivals.
“I think it can be a statement, but we just did really well and we focus on us,” Kuhn added.
“There is a still a long way to go, but we are going to focus on ourselves and, if we keep performing like this, everything is in our hands.”
