He wasn't there...
Lille is still fighting for gaining a champions league spot and possibly even the title, although that's a longshot. They've got a game on wednesday against Nice and had a training on monday and tuesday morning.
He's not going to hop around to watch a game in Manchester at the crunchtime of the season. Surely he would've been sighted there and a bigger fuzz would have been made of it mondaynight. Haven't seen one bit of evidence he was there.
Hope City get him btw, would be a huge statement of intent and directly launch the club to bigger European ambitions. Like I've stated here before, I've been a huge fan of Hazard since he was 16 and delivered the goods on the European -17 championship. You needed to blind to ignore the talent he displayed there. The best player to come out of Belgium since Enzo Scifo and imo on his way to be the best ever. Been following him closely ever since, not hard since his play is so pleasing on the eye of footballfans. (Love Dembélé of Fulham for the same reason!)
The latin style of City with the interchanging positions is very similar to that of Lille and I'm convinced he would be an immediate success here. Those who're thinking he'd be playing 2nd fiddle are mistaken... He's a potential Golden Ball winner one day and would dictate the way City play alongside Silva.
He wouldn't fit in at Utd who have that very rigid 4-4-2 where players aren't as freely to express themselves. The way City play with the little flicks through the centre between Silva-Aguero-Nasri-Tevez are right up his alley. The only other team in the EPL he'd fit in is at Arsenal but they won't be able to compete with the transferfee or the wages. (Hazard is already on +5 milion € at Lille!)
So unless Barca or Madrid come knocking, he's coming to City next year.
