Well... Just do the maths and I guess its the right time to go considering the new tax rate of 50% comes into play in April...
Going to Barce in the new season will see him get tax only 23%. Somemore with a higher weekly salary of €120k a week compare to what he is getting now roughly on around $80k weekly... So I guess its a no brainer to stay... cos even if the "Beckham rule" was to be abolish in Spain, he will still be tax at only 40% of his new improve salary... compare this to his lower pay at $80k and higher taxation in England... The wife also becomes a convenient piece of excuse...
We just have to assume he gets €120k a week at Barce, after 23% tax he will still take home = €92 400.
Even if after 40% tax, he still takes home = €72 000.
At Pool, he currently gets around pounds $80k, after current 40% tax, he takes home $48k a week... But if its 50% tax... It wll mean he takes back $40k a week only...
So which ever way you look at it, its still a good deal to go unless Pool give him a big pay raise cos the pounds and the euros are almost about the same this days...
