My answers for what its worth to the questions:
Questions can be asked over all of these players.
Lia - great stalwart for us. Given heaps. But time and quality of A league midfields has moved on. Looks a better player under Ernie, and will never slag him, or Muscat, as they came to live and play in Wellington, when dozens of midfield type players didn't want to, and apparently still don't.
Caira - too early for me to judge. Like Fenton gets little support. There was so little confidence knocking the ball around last night by so many in the back third, you'd think they were playing on a minefield.
Huysegems - giving a lot of quality at the moment - but unlikely to hold on to an import spot if we can do better.
Cunningham - think he's a quality player, who like Hernandez looks around at the rest of our midfield and says WTF.
Hicks - completely out of his depth.
Riera - too early for me to decide. I just think we have to get better midfield players than Hicks and Riera, though Riera's currently In Ernies top midfield lineup (which he said last night post game is Hernandez, Lia and Riera)
Bertos - finished
Adams - not seen enough either
