Apart from the fact that you are referring to 13 years ago or more, Martinez showed him how to properly use full backs in his first season.
….i think it was Chelsea away, we drew 3-3 but we’re winning late on. I apologise if i have some detail wrong.
We were winning comfortably and our RB was our furthest player forward. Suicidal, Fabrigas launched the ball forward early as he always did, Stones was having to cover vacant RB, Baines was forward on the left and we were so exposed with just Stones and Jagielka back. Chelsea scored.
It told me everything about how not to use full backs, talk about naive with both getting ahead of the ball. You watch, you learn.
