Lille's stadium is smaller than Pompey's man, they may be in the Champions League, and (until the end of this transfer window anyway) have a great little squad, but there not a 'big club' by any means, there going through a honey moon period and will probably be off the map within a year of 2. They havn't got the tools to keep this up imo, and this is probably what the players who are jumping ship see aswel.
