Celtic boss Neil Lennon hailed guiding the club into the group stages of the Champions League as his best achievement in football.
The Scottish champions booked their place in the lucrative group stages with a 4-0 aggregate win over Helsingborg after a 2-0 victory at Parkhead in the second leg of their play-off clash.
It is the first time in four years Celtic have reached the group stages and Lennon admits he was under pressure to get the club back among Europe's elite.
"It's the best thing I've done in football," Lennon told Sky Sports HD 2. "The pressure going into this game and, in particular the last five or six weeks, has been enormous.
"I actually feel British clubs going into these games are at an unfair disadvantage because they're starting their season, so it makes the effort of the players and the performances even more remarkable in the circumstances."
Lennon was delighted for everyone connected with the club to be in Thursday's draw for the group stages.
"You know what it means to the fans here and the club," added Lennon.
"It's been four years in the waiting and I'm just so happy and so proud of them."
