UEFA Champions League: Celtic have second chance
Celtic will hope to make the most of their reprieve when they meet Maribor in the UEFA Champions League play-offs on Wednesday.
The Scottish champions lost their third qualifying round tie 6-1 to Legia Warsaw, only to be reinstated after their opponents were found to have played an ineligible player in the second leg.
That meant UEFA overturned Legia's 2-0 win and handed Celtic a 3-0 'walkover' win - enough to see them progress to the two-legged play-offs on away goals.
The issue has rumbled on ever since, with Legia first asking Celtic for a one-off winner-takes-all match before appealing UEFA and then the Court of Arbitration for Sport to reverse their decision.
With Celtic again heavy favourites to win the Scottish Premiership in the absence of Rangers - who are in the second tier - the Champions League is of huge importance to the club and they will be determined to make the most of their good fortune in Slovenia.
With spots in the group stages of Europe's premier club competition up for grabs in the 10 two-legged play-off ties, Celtic will hope they have caught Maribor at the right time.
They slipped to a surprise 3-1 defeat against Celje on Saturday, while Celtic thrashed Dundee United 6-1.
Celtic manager Ronny Delia said ahead of Tuesday's clash: "I'm always optimistic but we have to keep on working hard and believe in what we're doing.
