The Hoops have been trailing the Maritimo striker for months now and hoped to secure the services of the Senegalese ace during the current tranfer window.
But last night it emerged that Bundeliga giants Stuttgart had already tabled a £5m deal for the hit-man who bagged another double in the Portuguese Cup last weekend to take his goals tally to an impressive 13 for the season.
And with wealthy Chinese outfit Beijing Guoan also entering the bidding war and set to offer mega wages the Germans have told Diawara's Portuguese club that they are ready to up their original offer this weekend in face to face talks !
"The more goals Baba scores the higher his valuation " said a Maritimo director.
"We have placed a £6m figure on his head and expect to get it within the next few days."
