Absolute rubbish. If he's quitting for ambition would he join any one of the so-called big clubs for a reduction in wages? Not a freaking chance. He's an elite professional footballer and they live on earning ridiculous sums of money...and still wanting more.
Your deluded.
Sign for a big club but take a reduction in wages? Its not some moral highground. You dont be a 75m player and get a reduction in wages.
Its only natural his wage will increase.
