Maxi is 30 going on 31? Its actually a nice out clause for him to go as he sees players slotted in front of him very soon. He has never complained about lack of games, a good squad guy to have around. Its good for both sides. But his side value is he , Lucas, and Suarez hang out with each other if you look at their FB and twitter messages. His value at being "good mate" on the club for Spanish speakers is what he helps the team the most. Maxi is a classic glue guy on the bench.
We won't know if its "Sensible" until we see if they pan out. And at the cost versus other clubs in a similar position like Spurs or Juve, teams fighting to get to CL. We will see in a few years.
And Downing for 20 mil...I would be disheartened a bit as well when N'zogbia is quoted out at 9 mil by his club. If we are stuck shopping 2nd tier players, then lets at least get value?
