This is gas.

Glasgow Warriors are currently trailing Premiership Champions 13-3 at half-time in their Champions Cup pool match as Scotstoun.

A Michael Rhodoes try has been the difference between the two sides so far along with a couple of penalties from England international Owen Farrell.

Glasgow however, thought they had gone themselves back within touching distance just before half-time through a DTH van der Merwe, only to discover the ref had already blown his whistle.

The Scottish side didn’t hear the whistle initially and broke into wild celebrations – but Maro Itoje did. The England lock then proceeded to wind up his opponents by joining in on the celebrations. Brilliant stuff.
