Despite his 70% remark last week that played up the fan's own prejudices about lack of fitness as an issue, I bet Koeman doesn't look at this squad and immediately think: "If only I can get this lot up to 100% we can go places". More likely he's thinking: "Where is the intensity and spirit of these players? They look suited to a different possession based game rather than the sort I want, I'm going to get rid and buy in new players".
The solution here wont be conditioning it'll be an open cheque book.
