Celtic defender Mikael Lustig has praised his teammates for an "unbelievable" achievement after they made it through the entire domestic season unbeaten.

A late Tom Rogic strike helped the Hoops to defeat Aberdeen to win the Scottish Cup yesterday, ending a season that also saw them claim the Scottish League Cup and win the Scottish Premiership by a 30-point margin.

The feat marked the fourth time that the Scottish club have managed a treble, and pundits have drawn comparisons between Brendan Rodgers's current side and Jock Stein's infamous Lisbon Lions side that claimed a historic European Cup in 1967.

"What a season it's been and what a team. It's unbelievable. To go through the season unbeaten and lift three trophies - I don't know if we'll see that again," Lustig told reporters. "We can all retire now!

"No, we still have a lot to learn. We still want to get better and improve in Europe. But to win a treble, not losing a game, it'll be tough to beat.

"All the boys were nervous going into the final because we knew we had a chance to write history. But we did and hopefully we can take more steps in the right direction now. We always felt that we would create chances to win the game. We just had to remain calm. It's easy to be good when you're with good players, you're confident and you're winning games. It's difficult for teams to handle us, the way we play.

"It's a strange feeling to be mentioned alongside legends of the club. If you look back at the teams to do a Treble, there were some great players. It's unbelievable for us. To be part of making history at this massive club is really good."

Celtic return to competitive action in just six weeks when they begin qualifying for the Champions League.
