Arsenal Vs Manchester City: 5 things we learned – Nothing’s changed

2. David Luiz can say goodbye to second season

David Luiz is renowned for these types of performances. On this occasion, he squeezed his errors into 25 calamitous minutes. He initially started on the bench, was introduced for Pablo Mari on the 24th minute, and by the 49th has conspired to commit the crucial mistake in the build-up to City’s first goal and then foul Riyad Mahrez, conceding a penalty and a red card for City’s second.

Luiz is well-paid. He has cost £24 million for the one season he has thus far spent with the team. Rarely has he lived up to that price tag. Initially reported that he signed a two-year deal, it was later revealed that Arsenal would have to negotiate a new contract with the Brazilian. It was, however, expected that the two parties would come to an agreement.

That may now be in doubt. Luiz has been renowned for his leadership and high-character, but his play on the pitch has not measured up to his cost. This season, he leads the Premier League in red cards, penalties conceded, and errors leading to a goal. Per Duncan Alexander, he has been sent off once every 13 games and conceded a penalty once every 6.5 games. That is not the type of centre-back you keep.
