However, the former West Ham boss also admitted that if any players are offered improved deals elsewhere, the club will not be able to compete financially after learning lessons from past seasons. \"All of our best players are on long-term contracts, so I would be very, very surprised at them being linked with other clubs,” Pardew told reporters. \"I think anyone who looks at this football club will know we are difficult sellers. \"Someone is going to have to pay a lot of money to take one of our players away - especially considering where we are right now, and are having success. \"We have some really, really good players. My focus is to ensure that they are focused, because we still have three games in what I call The Tunnel - you know, before we get to the last six, [when] you can see the finishing line, you can see a goal, you can see a European place or safety or survival if you are down the bottom. There\'s something you can see or smell. \"But this period of games, as a manager I really have to focus my team. If we can get one win and something from the other two, or get a couple of wins, then we are really well set for the last six. \"If we do it, it\'s not just a great reward for the players but it will help attract players and that is also beneficial to our European stamp of approval. \"I said last week, we must now focus on that - change our goals to focus on Europe.\"
