Martin Dubravka wants Newcastle to soften their stance and allow him his dream move to Manchester United.
The Old Trafford club turned to Dubravka last week after being quoted £21m for Frankfurt's Kevin Trapp.
The 33-year-old Slovakia international was left out of Newcastle's midweek Carabao Cup win over Tranmere after officially being declared 'ill' as talks picked up between the two clubs.
United have asked to take the 33-year-old on loan with an option to buy but Newcastle are insisting they want a straight sale for £5million.
