Celtic fans have reacted to former Hoops flop Teemu Pukki netting a hat-trick for Norwich City yesterday to hand the Canaries their first win of the new Premier League season.

The Finnish striker was monumental for Norwich last season as they won promotion to the big time, scoring 29 times in the Championship.

Impressive Pukki hits treble against Newcastle

His rich vein of form doesn't appear to be slowing down, either, as he's already bagged four goals in his first two games in English football's top tier.

A treble against Steve Bruce's Newcastle yesterday afternoon saw him shoot up to the top of the scoring leader board already.

And Hoops fans can't believe he's the same player who managed just nine goals in 37 games during his miserable time in Glasgow.

One supporter posted on social media: "Said it last season but that teemu pukki cany be the same player that played wae Celtic".

Another joked: "Teemu Pukki never scored a hat-trick in the SPL when at Celtic. The Premier League must be a pub league".

One wrote: "How’s Teemu Pukki pulling all this off seriously one of the worst strikers to ever put a Celtic shirt on".

A fourth added: "teemu pukki, celtic reject, scoring in the "best league in the world" again there".

Pukki netted against Champions League winners Liverpool on the opening day at Anfield in a 4-1 defeat for his side.
