Man City chief Cook: Players know anyone could be sold
"Mark said he would like to bring a couple of players in for those positions but, when we went out to find these better players and then they didn't come, we were left holding the baby.
"We didn't want to sell players and have no replacements, but players must know that in the football world everybody is for sale.
"Mark's point is that we have some great talent at youth level and a bit older than that. We just need to fill that gap in the middle. We need players with Premier League experience in key positions.
"When you get to the dead of winter and people start pulling the gloves on and the tights on, it's bloody hard for them.
"Mark is saying: 'We need some people with some mettle'."
