He may have opened his account for PSG in Europe, and terrorised Celtic once more, but Neymar's refusal to shake the hand of Celtic's rookie right-back Tony Ralston hasn't gone down well.
The world's most expensive player opened the scoring in PSG's 5-0 drubbing of Brendan Rodgers' side at Celtic Park and he also had a spat with Ralston, who was making his Champions League debut at the age of 18 and had only played four competitive games prior to tonight's outing.
Considering the task at hand, he acquitted himself fairly well and his passionate performance went down well with the Celtic faithful. He was involved in a bit of beef with Neymar in the second half and proceeded to laugh in the Brazilian's face when the former Barcelona man uttered words at him.

Having clearly spotted the young defender's offering, Neymar decided to shake the hand of his teammate Marco Verratti instead.
And as seen in the above clip, the PSG No.10 continued to have something to say to Ralston as his teammates intervened to try and defuse the situation, before laughing and winking at his opponent.
