David Luiz delivered one of the all time disastrous Arsenal performances last night, and it could be his last.

The Brazilian’s error led to Manchester City’s opening goal, before he gave away a penalty and was sent off minutes later. And he had only come on as a substitute.

Luiz may now never play for Arsenal again, as he will have a suspension to serve, and then Mikel Arteta might simply turn to his alternative options.

Luiz panning out to be a disaster though is no surprise. He has always been a risky and error prone defender, and Arsenal panicked on deadline day by buying him.

It was a cheap stop-gap deal, and Arsenal truly got what they paid for.

But the real fault here lies not with Luiz, but the decision to spend £72 million on Nicolas Pepe.

Few knew Arsenal had that kind of money to spend last summer, and when they did, there was hope and belief that he may emerge as a superstar.

Pepe has talent, and might eventually come good, but he hasn’t so far.

He was not even in Arsenal’s starting line up last night, which says it all.

Arsenal mismanaged their funds last summer to blow £72 million on an extravagance in Pepe, who has been a big disappointment so far.

This left £8 million to spend on a centre-back, and in Luiz, Arsenal had few options.

There was one bit of smart business, in William Saliba, who was loaned out, and he will come back and strengthen Arsenal, replacing Luiz next season.

Perhaps it will work out. Pepe may come good, and Saliba will be a superstar. And then we will have a new perspective on Arsenal’s 2019 summer business, with the year of David Luiz a horrible memory.

But right now, in the moment, it seems as though Arsenal have messed up, and spent £72 million on a winger they don’t need, when they could have bought two £40 million centre-backs instead.
