Reports in Italy suggested Diego's agent had been in Turin last week for talks with the Bianconeri.

But Allofs revealed he has spoken personally with Juventus and been given assurances they are not interested in the 23-year-old.

"Juventus are not bidding for him," he told Premiere television.

"I have spoken to Juventus' management - they actually came to us. Juventus are not interested and these are all only stories which keep being repeated.

"Diego has a contract with us until 2011 and there are no considerations at Werder to let him leave before then."

Allofs believes the speculation is down to Bremen's current struggle for form and the assumption Diego is unsettled by it.

But while admitting to being in a difficult phase, Allofs is not giving up on his players, who he believes will turn the corner despite another disappointing result on Saturday - a 0-0 draw at Bochum.

"Even if you qualify for the Champions League five times in a row, that doesn't mean it's so obvious it will happen again," he added.

"That is perhaps too ingrained in the minds of the players and they think everything will just fall into place.

"The task now is to get that notion out of their minds.

"I can repeat once again I have no fear with regards the quality of the players."

Bremen lie in 10th position in the Bundesliga, eight points behind league leaders Hoffenheim, who have a game in hand.
