Why is it? Let's look at it like this.
Austin, Boufal, Rodriguez, Ward-prowse, Yoshida, Van Dijk, Targett, McCarthy out injured and the players that did play against Liverpool like Romeu, Redmond, Tadic etc put in such a monumental effort that they needed the rest.
If we'd played them they'd have been ****ed against Swansea and we need some momentum in the league. We got a tough draw, we surrendered but we are in a cup final anyway.
What exactly is there to moan about?
