Nesbitt said: "It’s a great feeling. This takes me to 2019, so it gives me plenty of time to keep developing and getting better, and hopefully becoming a good first-team player here. The manager has been telling that if I keep progressing the way I’ve been going, where I’ll be and where I’ve got the potential to get to as long as I keep working hard, and that’s what I’m going to do, to hopefully fulfil that potential."
Nesbitt is one of the most highly rated prospects in the Celtic academy, and the 18-year-old has already made his first-team debut for Deila’s side.
He came off the bench in the League Cup tie against Raith Rovers earlier in the campaign, making a short cameo, and then following that up with an impressive performance in the UEFA Youth League.
He scored a hat-trick in a 5-0 win over Helsinki, and the youngster is set to continue developing with the Under-18 side this season, whilst also hoping to further break into Deila’s side.
He will face a tough challenge to appear for more than a few minutes in the senior side this term considering the quality of Leigh Griffiths and Nadir Ciftci ahead of him.
Yet, the Celtic management clearly have faith that Nesbitt has a great future ahead of him, and tying him down until 2019 guarantees that he will develop under Deila’s watchful eye.
He may struggled to break into the senior side this season, but there are no doubts he will continue to fight for a first-team role in the coming years, with youth still on his side.
