Read what LDN said. You can't single out Luiz for "costing us the title" the whole team needs to perform well & together as a unit. They failed to do that. Exactly. Failing to create - Failing to score - Failing to win - Failing to win the title.
You need to get over that. They have done more great things for this club than bad. Luiz is a future Chelsea legend & you can see he will contribute to success even in these early stages.
Well that's over. At least it wasn't lost through any dodgy decisions. Just a plain shit performance. Big changes needed in the summer. Fresh new squad.
