Could it be that the paths of two clubs to have already generated continental friction this season are about to cross in the last-32 of the Europa League?
There is a chance that Celtic and Legia Warsaw will be offered the opportunity to resolve their differences in the heat of on-field battle, with both in Monday’s draw for the start of the knockout stage.
Legia were left fuming over the summer when they were booted out of the Champions League for fielding a suspended player, with Celtic reinstated in their place.
The Scottish champions were unable to progress past Maribor, though, and ended up dropping into the Europa League.
A grudge match with Legia would generate plenty of interest, in Glasgow and Poland, but Hoops boss Ronny Deila claims he will be happy with any pairing that brings a full house to Parkhead.
He said in the Daily Record: “I haven’t thought so much about it. It’s going to be a hard draw whoever we get. We’re going to meet a good club.
“We want a good draw so we can fill the stadium and get 60,000 here which is the atmosphere we want. Everybody is beatable but some are harder than others.
“Would I like Legia Warsaw? They’re a good team of course and it would be special if we got them.
“Hopefully we will get someone else but our players will be up for the game whoever we get.”
Celtic finished second in Group D behind free-scoring Red Bull Salzburg, while Legia topped Group L ahead of Turkish side Trabzonspor.
While a meeting between the pair would provide an intriguing challenge for both sides, Deila will be aware that there are bigger ties to be had.
Inter Milan, Napoli, Fiorentina, Sporting Lisbon, Athletic Bilbao and Zenit St Petersburg are all possible opponents, along with Premier League side Everton.
