Patrick Roberts wants to end his "fantastic" time at Celtic by making history.

The 21-year-old winger will return to Manchester City at the end of the season after the conclusion of his second loan spell at the Parkhead club, the first coming under former Hoops manager Ronny Deila.

The ex-Fulham player will bow out in the William Hill Scottish Cup final against Motherwell at Hampden Park on Saturday, where Brendan Rodgers' side have the chance to complete an unprecedented successive domestic treble.

Roberts said: "Yes, obviously I have been on loan and I will go back there when the cup final and the Scott Brown testimonial (on Sunday) is over.

"It has been fantastic. I couldn't have asked for any better.

"I came in January (2016) and played the back end of the season, scored a few goals and won the league, which was a good start.

"Then the manager (Rodgers) came in to get the treble, and to carry it on has been incredible.

"Coming to an end at any club is hard, especially for how long I have been here with the support and love I have got from Celtic fans and I have for them.

"It will be tough but that's what happens in life, you move on and hopefully it can end on a high.

"That's the aim. To get the double-treble would be something.

"All the boys are looking forward to it, we are focused for it and that is the main aim for all of us, especially for me, in the last game, to end it with a positive result and a trophy.

"I know I haven't played as much - which is down to injury - which is unfortunate, disappointing for myself. But for the team to kick on and continue their success from last season and put in the performances they have done, has been good."

Roberts, who joined City in 2015, stressed the importance of his time in Glasgow.

"I have grown as a person and a player," he said.

"I didn't play many games at Fulham or Man City. I have played nearly 80 games for Celtic, I have matured as a player, I have won trophies, played and scored in big games.

"I can take a lot and can come away from here having a successful time at a club - one I can cherish for the rest of my career."
