Alan Pardew: "It was a little strange as we had obviously put a lot of work in and made the club an offer that was accepted, a good offer.
"We made a fantastic offer to the player and then he didn't arrive. This club is on a financial footing that is strong, but we're still not going to pay silly money.
"We're going to pay what is correct and that is what we offered.
"We made a fantastic offer, a fantastic Premiership offer to that player - trust me.
"I don't really want to criticise the player. The player makes the decision and he stands by it. I don't really have anything else to say on it.
"We're going to sit down next week and hopefully iron out the issues and come to the conclusion that Colo stays and obviously that's what I hope for as a manager.
"It's obvious that there is a problem there in his life.
"The best way of dealing with it sometimes is to be on a football pitch and play your best football and he certainly did that last week."
