Arsenal suffered an early setback in their Premier League clash against Liverpool as key center-back William Saliba was forced off the pitch due to injury within the first five minutes of the game. The incident occurred early in the high-stakes match at Anfield, causing immediate concern for the Gunners and their supporters.

Saliba went down after heading the ball. Details surrounding the nature and severity of the injury are still emerging, but the player reportedly kept his left leg straight and his right leg bent. The sudden loss of such a crucial player represents a significant blow to Arsenal's defensive stability and overall game plan.

Manager Mikel Arteta was compelled to make an early substitution, bringing on new signing Cristhian Mosquera to replace Saliba in central defense. Mosquera, now thrust into the heart of a critical Premier League encounter, faces a daunting task in attempting to fill the void left by the injured Saliba.

The timing of the injury could not have been worse for Arsenal, as they are locked in a fierce battle with Liverpool, with both teams vying for the top spot in the Premier League. Saliba's presence in the Arsenal backline has been a cornerstone of their defensive solidity, and his absence will undoubtedly be felt.

It remains to be seen how Arsenal will adjust their tactics and defensive strategy in light of Saliba's injury. The onus will be on the remaining defenders to step up and maintain their composure against Liverpool's formidable attack. For Liverpool, the early injury to a key Arsenal player could be seen as a potential advantage, but they will still need to capitalize on the situation and maintain their focus throughout the match.

Arsenal's medical team will be working diligently to assess the extent of Saliba's injury and determine the appropriate course of treatment. The club and its fans will be anxiously awaiting updates on his condition, hoping for a swift recovery. This is another issue for Mikel Arteta to deal with.
