Croatian coaching legend Predrag Racki can't rule out Dinamo Zagreb selling three of their stars to Manchester United.
United have been linked with a £30 million move for Alen Halilovic, Sime Vrsaljko and Mateo Kovacic after a visit by United chief David Gill last week.
Racki remarked to Jutarnji List: "Just once in my life I experienced one club at the same time bought three players from the same club. It was when Milan from Ajax took Gullit, Van Basten and Rijkaard.
"I'm not saying it's impossible, in football anything is possible, but unlikely."
