Clark is our best-performing defender so shouldn't be moved. Gamez doesn't look a liability so play him until he proves otherwise/Mbemba returns.
I'd like Shelvey back in the team for a home game against difficult-to-beat opposition. You can make a reasonable case for that being at either Hayden's or Perez's expense.
Good question. Probably the same reason Ashley & Co think they can get away with it.
There are six Premier League clubs with a lower net spend than us. If Rafa stays there will be six clubs with shorter odds for relegation than us.
For reference: http://www.mirror.co.uk/sport/football/transfer-news/premier-league-net-spend-how-8745765
According to that, only 5 of the 20 Premier League clubs had a net spend greater than £35M during the last summer transfer window.
