Celtic vs Barcelona: Lionel Messi fights his illness and then the cold at Celtic Park training session
Argentina superstar has only just recovered from illness and would not want to catch a chill before kick off
BARCELONA may be able to handle the heat - but how do they get on out of it?
Catalan stars trained at Celtic Park on Tuesday night ahead of their Champions League clash with the Scottish giants on Wednesday.
But the biting cold temperatures seemed to be too much for Lionel Messi and Co as they were snapped in full length tracksuits and their faces buried deep inside their snoods.

Messi, who only just recovered from illness in time to be fit for the European encounter, took several steps to ensure he was not fully exposed to the two degree temperature in Glasgow.
Pictured rubbing and breathing on his hands, he still looked in good spirits as he hopes to help keep Barca top of Group C - above Manchester City - with a win against Brendan Rodgers' Celtic.
When the two sides met in September Messi bagged a hat-trick as Barcelona steamrolled the Hoops to a 7-0 win at the Nou Camp.
But Rodgers insists Celtic were only IMPROVED by that result - not harmed.
The Scottish champions have taken two points from four European games and need a win in their final two matches to have any chance of Champions League football after Christmas.
Rodgers said: "Out there, we made a very bad start to the game, going 1-0 behind, we had the opportunity to equalise, we had threats on counter attacks.
"Obviously we didn't get (score) the penalty and very quickly they get the second goal.
"And once Barcelona - like they have shown many times against better teams than ourselves in all honesty - get that rhythm and that flow in the game, it is very hard to contain it.
"So lots of learning came from that, lots of development both in terms of our team mentality and our game, came from that performance.
"At the time of course, I said it was very disappointing but it hasn't harmed us, if anything, it has only improved us a group and as a squad."
