I think you need a reality check pal...
Voronin = 4Mil at the most.
Santa Cruz = will not leave for more than 20Mil+
Glen Johnson = Will cost us 10Mil+ due to him signing a contract.
Babel = Agree with that price.
Alonso= We would never sell him for 15Mil. Juve offered us that last season. 20Mil+
Bentley = Considering they bought the lad for around 16mil, they wouldnt sell him for a pathetic 5mil.
Downing = Agree with that providing they get relegated.
Dossena = I couldnt put a price. Maybe 4-5mil.
Like Joel said could be wrong. But I think your estimates are way off. Inflated prices now pal in this transfer market.
