When asked if he was worried about Buendia leaving, he said: "No, nothing will happen. In this business you can never say 100 per cent guarantee, but I would label it 99 per cent.
"It makes no sense for any of my key players to leave at this moment. And it makes no sense for us as a club right now to sell any of my players.
"These players have the potential to play for one of the best clubs in this country, and Arsenal [are] definitely one of the best in this country and also Europe. They have the potential to play there one day, but it makes no sense in January. Let's be honest we are in a great position.
"Nearly at the end of January, and in less than four months the season will be over, and there's a good chance they then are a key part in a club in the spotlight at the top level. The club trusts you, the coach trusts you, the fans love you, it's a fantastic position to be in. If then there's a club that's really interested, a big club in this country or Barcelona, Real Madrid, Bayern Munich and they say 'you are our long-term solution', then there's always a deal possible and it's pretty likely, and we have to say 'come on' the player has outgrown the club. But not January. It makes no sense.
"Also for us we're not desperate to earn more money. Financially we are in a solid situation. We want to have success, and don't want to risk our chances to go back to the Premier League level. Also from a financial point of view it makes no sense to sell a player for £15-£20m.
"I think if there is a route for one of my best players, then it's definitely the summer. It's better for them, better for us, in the summer it could be a topic but in January I don't see any business."
"I have been in touch with some people close to the player today. They say the situation is that the player himself is focused on his job at Norwich. They are doing really well in the Championship, top of the table. They can see the Premier League on the horizon.
"The problem Arsenal would have with trying to sign him this month is how much it would cost. Norwich are a very well-run club with a sustainable business model. I have been told it would take a crazy offer for them to be tempted to sell him this month. A crazy offer we are looking at somewhere between £40m and £50m."
