Norwich City’s Teemu Pukki is leading the Premier League goalscoring charts with five goals, which includes a hat-trick in his side’s 3-1 victory over Newcastle United.

It now seems a long time ago from his Celtic troubles.

The Canaries signed the 29-year-old on a free transfer in 2018 and he was instrumental in their promotion to the top flight, scoring 29 goals and registering nine assists in the Championship last term.

Before the summer of 2018, things weren’t so good for the striker as he’s failed to impress at his previous clubs including Schalke, Celtic and Brondby.

The Finland international spent the 2013/14 season with the Bhoys, but was only able to manage seven goals in 33 appearances across all competitions.

Ronny Deila managed Celtic for two years between 2014 and 2016 and in his first transfer window, he allowed Pukki to leave the club. He has now admitted regret at sanctioning’s Pukki’s move away from Celtic Park.

“He played my first matches at Celtic, but it seemed like the club was a little too big for him at the time. It may have been a mistake [letting him go out on loan to Brondby], as seen in retrospect,” Deila told Norway’s TV2.

Deila is impressed with his former player’s performance in Norwich’s first league fixtures.

“I’m impressed with what he’s doing in Norwich now. When I saw the game against Liverpool, he was really good, so it’s not a coincidence that he scores as much as he does,” he added.
