Newcastle manager Eddie Howe, speaking to BBC Sport, said: "Big result for us. Difficult game today, knew it was gonna be. Brentford are a difficult team to play against. It wasn't a game of many chances didn't think, thankfully we got the important goal we needed.
"I don't think we were in full rhythm today but that's what Brentford do, they disrupt you. It was a bitty game for us, we had to set-pieces right, crosses right and defensively I was very pleased with us today."
On Elliot Anderson and Harvey Barnes: "I think they did really well. I'm happy Elliot got to start today because he deserved it. Harvey came into the team, performed well. They both did well in the international break and I have no problem putting them in."
On the penalty decision: "I have got no idea to be honest, I didn't see it at the time and I haven't seen it since.
On goalscorer Callum Wilson's new contract: "He is a leader in the group, a vocal presence, a positive guy and a goalscorer. Put them together and he's very important so I'm very happy he's staying with us."
