And that's why you want Martinez to stay in charge and all those who understand what they're watching don't. It's really that simple.
You don't have to park the bus to shut the game down, but you should reign your full backs in and keep a good shape defensively to ensure you don't leave massive gaps, or 1 on 1 situations for the opposition to exploit.
That's why Martinez' system is so flawed. He used the full back behind the winger to bomb on to give the opposition full back a decision to make, go wide with the full back or stop the winger cutting inside. If it works it can look great, but if it doesn't we've left a big gaping hole behind them.
On the other side he has the left sided player cut inside to try and ghost in to the middle and have the left full back play almost as a winger. Again, if it works great, but if it doesn't it means the two centre backs are hopelessly exposed.
Add to that we rarely put pressure on the ball and it gives good players the chance to pick out passes like Fabregas did.
Advocaat sussed this last season with a very poor Sunderland side when they beat us at Goodison. Manager's are on to the style of play, and all Martinez does to try and fix it, is change the players. Hoping that Lennon's work rate may solve it. When he signed Alcaraz he admitted as much, saying how he admires the South American defenders who can defend 1 on 1, man to man.
I understand what I'm watching. Believe it or not I'm paid to watch it as well.
Now, that doesn't mean that my opinion is in anyway more important than anyone elses, but it's my perspective.
Why is that why his system is so flawed? Again, it's not Martinez's fault - personally - that Oviedo lost possession, or that Del did later on.
That was my point - that all the blame can't be laid at the feet of the manager - or at least not by the people who understand what they're watching...
