ALAN Archibald today warned his Partick Thistle players there is no chance Celtic will be suffering from a Euro hangover this weekend.

Archibald was at Parkhead last night to watch the Scottish champions overcome Dutch giants Ajax 2-1 in a Champions League thriller.

Last season the Hoops struggled domestically immediately after playing in major matches against continental opposition.

Indeed, Neil Lennon's side drew with Ross County, Hibs and St Johnstone after taking part in Champions League games in the 2012/13 campaign.

And Celtic also lost to Kilmarnock and Inverness Caley Thistle at home and County away following European outings last term.

But Archibald, who hopes to have Scott Fox and Aaron Muirhead available on Sunday - despite the pair missing training yesterday - believes they have learned lessons from those experiences.

He said: "I am sure Celtic will make some changes this weekend and bring in a couple of players. They played Darnell Fisher, for example, against Hibs on Saturday.

"I know they came unstuck after a few of their Champions League games last season, but I don't think that will be a factor against us this weekend.

"Neil has said he wants his side to win every game they play this season in the SPFL Premiership, to go the entire campaign unbeaten.

"They have not lost in the league this season, despite playing in European qualifiers and group games.

"You can see the difference in them this season. Every game they have played in after a Champions League match they have been quite strong."

Partick are on a high going into the meeting with Celtic after becoming the first team to beat Inverness at home this season at the weekend.

Kris Doolan goals in either half ensured Thistle triumphed 2-1 against Terry Butcher's high-flying side and picked up three points. Archibald, who locked horns with Celtic on many occasions in his playing career, admits his charges are looking forward to playing in the sold-out clash.

He said: "As soon as we got promoted, the first thing we looked for were the games against Celtic. There are no tickets available and it is live on television. These games are the reason you are a professional footballer."

With lethal predators like Teemu Pukki, Georgios Samaras and Anthony Stokes on the books at Celtic, the Partick defence is sure to be put under intense pressure.

But Archibald is confident in-form goalkeeper Fox can cope with the onslaught from their city rivals in a derby match all Jags fans are eagerly anticipating.

He said: "Scott had a few fantastic saves on Sunday. It was a very physical game, especially towards the end when they puts us under pressure with corners and long throws.

"But I thought he handled it well. He has picked up a knock and missed training, but I am sure he will be fine for Celtic.

"Bizarrely, given how well he has played, Scott has only had one clean sheet, in the first game against Dundee United at Firhill.

"But that is something that we are working on as a team and hopefully we will succeed in keeping another clean sheet soon. It would certainly be good to do it against Celtic."
