He's been playing poorly this season, not rated by his peers in that league
It matters not! Dennis Bergkamp was/is an Ajax and Arsenal legend. But either side of that he had a poor spell at Inter Milan. Doesn't make him a poor player. Maybe Weller hasn't settled where he is now, could be a whole host of reasons why he hasn't done good.
Anyone who wouldn't want him back in Cardiff must be crackers ! Think you could be alone there Osh
