Celtic midfielder Joe Ledley insists they are ready to grab their second chance of European glory this season after their Europa League reprieve.
The Bhoys were reinstated in the Europa League after Uefa expelled Sion from the competition last week.
Swiss outfit Sion were booted out of the competition for fielding several ineligible players during their 3-1 aggregate win over Celtic in the play-off round.
Ledley insists he has no sympathy for Sion and that he and his team-mates will be out to prove a point that they can compete in Europe.
"I have no sympathy for Sion whatsoever and it's great to be back in European competition," Ledley told the Daily Record.
"That's where Celtic belong and that's the main reason why I made the move from Cardiff City in the first place.
"It's important the Celtic fans see us in Europe playing against the best clubs and against the best players so it's all good as far as I'm concerned.
"We have not been in Europe at this stage for a couple of years now and a club of this size needs to be playing at this level.
Point to prove
"Also, the lads want to prove people wrong that we can do well in Europe.
"I know the fans will be planning a few trips now in Europe and that's fantastic.
"Hopefully they will enjoy the experience and we now need to improve from the Sion games. It's up to us to show the world how big this club is and prove to people we deserve this second bite at the apple."
Celtic have been drawn against Atletico Madrid, Udinese and Rennes in their group and Ledley accepts they will need to up their game to have any chance of progressing into the latter stages of the competition.
"We have a great squad and I think we can do well in this group," added Ledley.
"We will have sell-out games and the club would have lost a lot of money if Sion had gone through so it's a big boost to the whole club on and off the pitch.
"Once the dust has settled over this, we can get stuck into the scenario.
"It's a tough group but that's what European football is all about.
"You are playing at a different level than domestic football and we all need to up our game and do Celtic and their supporters proud."
