Mainz sports director Christian Heidel has admitted they want to sign Celtic target Cho Gue-Sung, but have been priced out of the market.
The Hoops are still regarded as favourites to land the South Korean World Cup striker, but Jeonbuk Hyundai Motors' price tag of around £2.65 million is proving a sticking point for clubs, with MLS side Minnesota United also confirming their interest in the 24-year-old.
And Bundesliga side Mainz have insisted they are not interested in a bidding war in Cho because they can't afford it.
