Arsenal legend Paul Merson was full of praise for manager Mikel Arteta.
The Gunners booked a place in the FA Cup final after an impressive win against Manchester City.
The unlikely result means Arteta could end his first half season in charge with a trophy, which seemed improbable when he took over.
Merson wrote in his latest column for Sky Sports: "Arsenal have a plan, they go and press when they have to, drop off when they don't, they play with high energy and counter-attack as a team.
"They were outstanding against Man City. That was David Luiz - there's no grey area - he's either 9/10 or 4/10. But when he plays like that, he's brilliant.
"Arteta has done an absolutely phenomenal job. It's the first time I've watched Arsenal in many, many years, and they have a plan.
"Man City were up for it in the second half, and Arsenal put themselves on the line. I honestly think he's done a brilliant job. I can't talk highly enough of him.
"Against Liverpool, Arsenal rode their luck, but that's Arsenal now. They can't play against Liverpool and Man City as if they are the favourites, they have to grind it out like Sheffield United have to grind it out. That's what Arsenal must do now."
