Branko Stoic, Louis Saha's agent, told Belgrade television station RTVBK that Manchester United will make an improved offer for the Fulham striker : "Negotiations are very hard. A new bid is coming, superior to the previous one.
"Sir Alex Ferguson did not give up on Louis Saha. I believe the transfer will go ahead during this week."
Fulham boss Chris Coleman has insisted Saha will not be sold after rejecting an £8m bid from Sir Alex Ferguson.
Coleman also launched a bitter public attack on Saha's agent after claiming Fulham were being "bullied" into selling the £12m-rated star.
Stoic said: "He is a manager for the first time and doesn't know what he is speaking about.
"It is just a question of price - will Saha stay for six months or leave in the next couple of days? Fulham asked for £12m and that is too high.
