2. Shkodran Mustafi not to blame
Shkodran Mustafi made the crucial error of the match, under hitting a horrible backpass that left Bernd Leno stranded and David Luiz with no choice to haul down Tammy Abraham in the penalty area and face the consequences, a red card and a penalty kick, which Jorginho duly converted. However, while he is obviously the man responsible for this specific moment of madness, Mustafi is not to blame for the impact it had.
The blame rests on those building the squad. It has been quite evident that Mustafi simply is not good enough to play for a top-six Premier League team for some time. These type of high-profile errors are nothing new. He has committed them with painful frequency for many years. And yet, Arsenal have persisted with him as a key centre-back in their squad.
There are lots of reasons for this, from Arsene Wenger’s blind faith to the club’s arrogance in their valuation of the player meaning they would accept nothing but the deplorable £35 million they paid to sign him, but ultimately the result is quite clear: Mustafi remains in the team despite not nearly being good enough. And this result is costing Arsenal time and time again.
