Mark Gicquel is currently ranked #81, and I don't think he will go any higher after this match. He is not in his best form, and worse players than Tursunov beat him recently. On the other hand, Dimitry Tursunov is 36th player in the world, but not really in form. He had a small injury issue, but I think it's all in the past now.
He had 20 days of tour resting and only training, so its really unreal to see him loose in first leg.
These two never played before and it will be a treat!

Good luck!
