Rasmus Hojlund bid farewell to Manchester United after Napoli's qualification for the Champions League made his loan move permanent.
United signed Hojlund from Atalanta for £72m in August 2023 and scored 26 goals in 95 appearances in all competitions before being loaned to Napoli this season.
Hojlund scored his 11th Serie A goal of the season in Sunday's 3-0 win at Pisa, his best return in a single top-flight season in the top-five European leagues.
The result guaranteed Antonio Conte's side a place in the Champions League next season, which Hojlund confirmed triggered a permanent switch.
"This goal felt symbolic because it means two things. We have now secured Champions League with Napoli, which means, because of my contract, I'm now officially a Napoli player, and I'm saying goodbye to Manchester United," Hojlund posted on Instagram.
"That feels weird, because for the past year I already feel like a Napoli player. The way you fans supported me, made me feel like home and let me find my confidence again is something I'm so grateful for.
"To say goodbye to Manchester United is something that kinda feels emotional too. My childhood dream came true by playing at Old Trafford in a red jersey.
"So the goal today symbolises a new confident start, in which I will give everything for the time ahead to Napoli, and a thank you to all the fans, players and staff of Manchester United who made the dream I had as a kid come true.
"It’s time for new dreams, so let's chase them."
Another player leaving United is Tyrell Malacia, whose departure was confirmed following the 3-2 victory over Nottingham Forest.
Malacia, who spent part of last season on loan at PSV, made 49 appearances for United after joining from Feyenoord in 2022.
"There's Tyrell, who I spoke to the boys about before kick-off," Michael Carrick said when addressing the fans after the victory over Forest.
"He's been through a tough time due to injuries. I encourage you to show him your support."
