Striker Gary Hooper has told his Celtic employers and the club's fans that they have still yet to see the best of him, despite his recent flood of goals.
The English forward has been in red-hot form for his club on both domestic and European fronts of late, firing seven goals in his last five games, including a four-goal League Cup haul against Raith Rovers.
Hooper's highlight of the goalscoring run, however, was the UEFA Champions League victory away to Spartak Moscow when he opened the scoring in the 3-2 triumph - the club's first away win in the competition's group stages.
The 24-year-old told the Celtic website: "The Champions League topped it off. That was the top of my whole career, scoring and winning away in Moscow.
"It was a tough game. They were a good, strong team and good on the ball, but I thought we stepped it up a level compared to the SPL. I felt that was the best trip so far.
"That game and scoring in the Champions League was a dream come true for me. It was up there with winning the league, cups and the play-off final, but I think it topped it all off.
"I don't think you can say you're at the top of your game as you can always learn and improve.
"There is more to come. I have scored three, four and five in one game, so the next target has to be six now! Scoring goals is a bonus but that's also my job as well.
"I think the whole team is playing well just now. We are creating enough chances to score quite a few goals and the job of the strikers is to score them."
