He told Sky Sports: "Based on the club's history, 10 per cent [chance of staying]. Because we know the philosophy of the club, I'm not attacking them. I know how they deal with players over 30 in the past and I know how the situation will be so I never expect the club is going to be, 'Okay, you have two years there'. We reach a point in the money [negotiations], all of us are happy so I didn't expect I was going to stay. I think it took six months for the negotiation to go really quick and I think from January, I go, 'Okay, now things are getting better and better'. It took a while. I think the club tested me to see if I can provide or not (laughs). I didn't want more than that, just the two years."
When asked who was more important to tie down to a new deal, him or Virgil van Dijk, he laughed and replied: "I think both. You need clean sheets and goals, without goals and clean sheets you won't win trophies."
