Watch this Irish rugby fan gatecrash Tadhg Furlong’s post-match interview

"Going away from home, we had to meet them horn on horn."

And that was only the start of it. Leinster went to Franklin's Gardens on Friday night and did a complete number on a Northampton Saints side that finished their Champions Cup loss with only 13 men. Leo Cullen's side recovered from a mid-game dip to finish with a flourish and get a vital bonus point victory. Saints ended up with Dylan Hartley sent off and George Pisi in the sin-bin - both were for high tackle offences. One of the key battles Leinster bossed was the scrum and tighthead prop Tadhg Furlong was a massive part of that dominant set-piece. In a post-match interview with BT Sport, Furlong spoke of locking horns with the Saints front row and Ronan O'Gara was loving it. https://twitter.com/RonanOGara10/status/807339797064941569 The interview was then made even more memorable when a jolly Irish fan crashed in and told the watching world about Furlong beating his brother in a fight. "We don't understand you," remarked BT host Sarra Elgan Easterby. Classic TV.

"We had to meet them horn on horn" @leinsterrugby's @tadhgfurlong delights in forward dominance. #ChampionsCup https://t.co/dLDT8IhoEA

It was another monster game from Furlong but, he knows, the job is only half done.
