Obvious aim this season should be to win a cup. After that, qualifying for Europe again by whatever means. The best way to improve your club is regular participation on the continent.
If, and it's a big if, Marveaux can stay largely injury free this year, it's a massive boost. He's got a cracking turn of pace and great control.
He'd be like a new signing, one may say.
Think the message is that if someone like Tiote went for 20m, we'd trust our judgement to spend the 20m to make us better off and a stronger squad than we were with just Tiote. I.e. to fund the signings of three 7m pound players such as Debuchy, Anita etc etc. If that's how it has to be then I'm comfortable with that.
