Injury prone
Another reason to avoid the attacker is that he is injury prone, Gourcuff, in his time at Lyon has missed close to 90 games with various injuries and playing in the Premier League is one of the toughest things you could do thanks to the rough and tumble nature of the game.
Gourcuff might be talented but simple bringing him into such a tough league would be suicidal for him and the team and hence Liverpool should stay away from the French attacker, who might find it better if he remains in France and playing for Lyon.,
