Was Saha in his younger days even seen as a big talent? Or was he just ignored because of other French strikers like Henry, Trezeguet and Anelka?
The Golden Boy award wasnt a thing in Saha his youth but i doubt Saha would have won it. Martial did win it, it doesnt say everything (or much at all) but it does show how talented Martial was considered at the time.
When Saha came to Manchester United he was a more developed player. He was 25 years old, he already played multiple seasons as a starter in France and in England. Its not that strange that he was a more complete, better and more developed player when he came to Manchester United than Martial was when Martial came to Manchester United. If you claim Saha was 'miles better' at 25 than Martial at that age (ruined by managers and injuries) i can understand it. However was Saha at 19 as good as the 19 year old Martial who signed for Manchester United? I dont know but Google tells me that Saha was playing for Metz in France and scoring 5 goals in 47 games. It looks like Saha started scoring goals for Fulham when he was around 22 years old.
Martial came to Manchester United as a hugely talented young player and looked great when LVG was the manager. Mourinho didnt like him and Ole didnt have a clue how to be a manager. If LVG stayed or a manager who liked Martial and knew how to develop players than Martial (without injuries ofcourse) would have been a much better player as he is now. Ole making Martial play through injuries also didnt help much for Martial his development... or long term fitness as we can see now.
Saying that Saha is better (in this what if scenario) seems a bit like looking back at the good old days, forgetting bad games Saha surely had, when Saha played in a much better team for the best manager while recency bias towards Martial is that Martial is always injured and cant even run at times. People seem to have forgotten how good and exciting young Martial was.
