Celtic will keep working at getting a new deal agreed with Victor Wanyama. Manager Neil Lennon is planning talks with the midfielder's agent, Rob Moore, who announced in October that Wanyama had turned down an extension at Parkhead. The Kenyan's displays for the Parkhead side have attracted interest from the likes of Manchester United and Queens Park Rangers. Wanyama current contract runs till 2015 and Lennon hopes that talking to Moore sooner rather than later will help to improve Celtic's chances of prolonging the deal. Lennon said: "We can always re-open negotiations with Rob on Victor's situation. He has another two years on his contract so we have time on our side. Obviously, the longer we leave it, the more vulnerable we become or the more he is an attractive proposition for a bigger club. That scenario will be a reality later on down the line. In the meantime, we will be plugging away at it. He has never intimated to me that he wants to leave and I am not too sure who is driving the bus in this situation, whether it is him or Rob. Further down the line I would like to speak to Rob again on the situation and see if we can bed him down for a little bit longer. Like everything else in life, you can't stop the progression. If a bigger and more productive club came in and the offer is right then we will seriously look at it. I don't want to stop their progress. I will shake his hand and say 'good luck to you son'. Just so long as we get about £25million."
