Hamburg manager Mirko Slomka says he is unsure the Bundesliga club have the finances to recruit Lewis Holtby from Tottenham.
The German outfit have been linked with a move for the midfielder, who spent the second half of last season on loan at Fulham.
And, while revealing his admiration for the player, Slomka cooled any hopes that the club could pull off a deal.
"Holtby is a class player," he is quoted as saying by Bild. "That is not up for discussion.
"But I do not know if it is economically feasible."
His comments come on the back of those made by Rafael van der Vaart, who expressed a desire to see Holtby join him at Hamburg.
"Holtby would be a great addition," he remarked. "It would be great if that would work.
"Lewis is flexible, he has great qualities."comments
