What I loved about watching him yesterday was his busting a gut to get back to defensive duties.
Monreal was the only FB since Sagna who did it when he was younger but he was not particularly adventurous so not on the level of Tierney whose offensive contributions from out wide should open a new dimension for us. It was understandable that, like Pepe on the other wing, the link-up play with the other players needs working on.
