Jota had initially joined Celtic on loan from Benfica in September 2021 and, following a successful season, the Glasgow club triggered a reported option to buy of £6.5m the following summer.

He helped Celtic secure the treble in 2022-23 and had scored 28 goals in 83 appearances by the time he was tempted to Saudi Arabia.

Jota described his return as “very nostalgic”, saying: “The best thing in Glasgow, besides Celtic obviously, is the people and I feel like I need a place with soul, where I feel at home.”

He had been signed for Celtic by Ange Postecoglou but says current manager Brendan Rodgers “was crucial” in his decision to return.

“We had really good discussions and we were very honest and, in the end, we believed in each other,” he said.

“I think it’s a really exciting time to be working with someone who has achieved so much and who is giving so much joy and happiness to the Celtic family.”
