Arsenal manager Arsene Wenger was left with even greater headaches regarding his available squad following Saturday's loss to Premier League title rivals Liverpool.
Wenger—who was already without midfielder Alex Song and new striker Gervinho due to their red cards last week, and midfielder Jack Wilshere to injury—was forced to utilize want-away midfielder Samir Nasri as his squad was stretched thin.
Nasri understandably received a mixed reception by the home faithful, but his performance on the pitch was bright despite the speculation swirling over his future.
Things quickly got worse for Wenger, however, as he was forced to substitute defender Laurent Koscielney due to a back injury after only 14 minutes of play.
Liverpool, meanwhile, struggled to break down their opposition in the first half, but things changed significantly after the break.
Young Arsenal midfielder Emmanuel Frimpong—who had been enjoying an impressive game up to that point—showed his inexperience by going studs-up into Liverpool midfielder Lucas, directly in view of referee Martin Atkinson.
Atkinson showed Frimpong a second yellow card, and Liverpool manager Kenny Daglish immediately introduced Raul Meireles and Luis Suarez, who changed the game for Liverpool.
In the 78th minute, Arsenal's Aaron Ramsay was unfortunate in opening the scoring for the opposition. Young Arsenal defender Ignasi Miquel attempted to clear the ball from the box following pressure from Suarez, bouncing it off the chest of Ramsey and into his own net.
Liverpool made it 2-0 and secured victory when substitute Suarez made the most of a Liverpool counter-attack in the 90th minute, tapping-in from close range.
