Arsene Wenger may just have been impressed by the goal scored by the man he says he wants to bring to Arsenal.

Lyon beat Rennes 2-0, with Grenier scoring his seventh goal of the campaign, and if it does prove to be his final match then it was a surefire way to sign off with style.
The attacking midfielder netted a stunning free-kick, one reminiscent of former Lyon maestro Juninho Pernambucano.
For Arsenal fans interested in what the player can do - it's well worth a watch...
Would Grenier be a good addition to Arsenal?
