I get your point but I just don't think Sanchez is a top class defender.I absolutely agree they are superior players but stick them in a system where they are coming under constant pressure and i think it may surprise people how many individual mistakes they will actually make.
He did this under Poch too when we played better football.
He just makes too many mistakes for all the good things he does.
Nothing about Sanchez screams calm and composed. Top CB'S like Toby/Jan gave u a sense of security which I just don't get anymore.
