I think people still don't understand the problem with Isla. He's playing mostly counter-attacking football with Chile, same as with Udinese. He has always done well in that kind of setup.
Isla has never been good in our possession game and never will, he just does not have the right attributes. He cannot beat his man, his technique is mediocre and his crossing is underwhelming.
Let's hope he continues playing well at the world cup so that we can sell him for more money.
