Barking 41-year-old Ray Parlour, a tenacious midfielder during his playing days and a three-time Premier League title winner with Arsenal, commented to Sky Sports after his former side's 1-0 triumph over Tottenham Hotspur that the match really was a "must win" due to their poor performance registered against Stoke City at the start of the month.
"The Rosicky half-volley was a great start," he said. "When you play football, you know when you catch it correctly that it's going into the back of the net. You could sense Rosicky, when he hit that ball… [he knew it was going in]."
Statistically, Spurs were impressive in retaining the ball, enjoying the lion's share of possession, while also attempting ten more shots (17) than their White Hart Lane visitors: "Spurs had their chances and put Arsenal under such pressure, they were unlucky not to get an equaliser."
The defensive solidarity enjoyed by Arsenal's central pair wowed Parlour, who added: "Koscielny and Mertesacker won Arsenal the game, they were different class as going forward they were poor but they showed determination and grit and they got that result."
That grit will be required come Saturday, when the Gunners introduce the weekend's bill of football with a lunch-time match-up with Chelsea at Stamford Bridge.
Win and Arsene Wenger's narrow the point gap with the Blues to just a solitary point at the top of the table, with second-placed Liverpool tasked with a Cardiff City game later in the day.
Parlour, though, believes the pressure will not be on Arsenal, who have an exemplary away record, but on Chelsea, who will not want to spoil their unblemished record in West London under Jose Mourinho's stewardship.
"There'll be more pressure on Chelsea to win the game. Maybe Arsenal can pick them off. I think they are going to go there and get points, even if they get a point it opens it up for the other teams.
"The last two or three games… I can see it going to the last game of the season!"
