I want a players first quality to always be effort, talent comes next. If a player is not willing to work hard they can do one as far as I am concerned. Perhaps why I supported the likes of Kuyt, Lucas and Henderson whilst they took stick of many fans!
Personally, I believe talent is the first criteria. Technically gifted players can compensate for their lack of effort but strong spirited players will never reach certain heights - use Spearing as an example.
I do understand what you mean though - players should have both qualities but I rather take a technically good player over a hard worker.
he know's some private detectives apparently.
