Mascherano proposed permant deal could be Liverpools last for a while i think.Especially with the way things have turned all messy at Anfield,and if the situation doesn't get sorted one way or another i may be speaking incorrectly,but it could be totally out of Liverpools hands to when they can buy or sell again.
With the in-house power struggle going on the FA may just step in themselves and inforce a temporary embargo until the matters arising are settled and finalised..
