Celtic manager Brendan Rodgers believes Adam Idah will be “crucial” to the Bhoys after his protracted moved from Norwich City was finally competed.

Idah has left Carrow Road after 17 goals in 116 senior appearances, having come through the club’s Academy.

The 23-year-old had a successful loan spell with Celtic last season, making 19 appearances and scoring nine goals, including a last-gasp winner in the Scottish Cup final to clinch the double.

He has signed a five-year contract with Celtic, a deal which will be worth £8.5m plus a further £1m in add-ons. The Canaries have also inserted a sell on clause of 15pc into the deal.

“The club has done brilliantly to secure this long-term deal,” said Rodgers. “We are investing in a player of real quality who will be crucial for us over the next few years.

“He is a player who already has given us so much, performing fantastically for us on loan and really delivering for the club and our fans last season.

'He played a pivotal role in our success last year and I know he can be hugely important for us again.

“Adam has fantastic attributes and he is a dynamic, hungry, committed player who can make a real difference.

“Really importantly, Adam feels at home at Celtic, he has a love and passion for the club and I know he will be giving everything to once again bring our fans success.”

Idah himself admitted the lure of returning to Celtic was irresistible.

 “I think everyone knew where I wanted to be,” he said. “It’s amazing for me and I’m delighted to be back.

'Within the first couple of days of being here when I came on loan first time, I wanted to play for Celtic.

"It was amazing to get all of those goals and to be in with the boys and to see these amazing fans week in, week out was unbelievable.

“I’ve never experienced anything like it and I’m just so happy to be back.

“I always wanted to play for Celtic and obviously last season was amazing. To come here now and be fully a part of the team and a part of this club is amazing to me.

“Everyone back home, all my family and friends, they all wanted me to come back to Celtic, myself included, so it’s massive and I’m just so happy to be here."
