Well, Alexis is only 1 year younger than Ben Arfa
Unless we re-signed Alexis last week without my knowledge that isn't actually relevant (If it were even true at all, Arfa is 29 and Alexis is 27). Alexis when he signed for Barca was 22. Ben Arfa right now is 29.
and the French league is the 5th best in Europe,
Being decent in the 5th best league does not translate to being good enough for the best team in the best league in Europe.
and is exporting great players every year and has a great NT.
Great players leave Serie A. Mediocre players join. Ben Arfa is an import from England. All the best NT players from France are playing in leagues outside of Ligue 1. With that logic Belgium has a great, tough league as well, because their team has a lot of great exported talents and their NT even made it far in the latest World Cup.
Ben Arfa was even called up for the France preliminary squad for the Euros.
And both Munir and Deulofeu have played in World Cup qualifiers for Spain as teenagers.
I think Munir would struggle greatly to score 10 goals for a mid table French team.
That could have easily been said about Ben Arfa if you looked at his career before going there.
Not saying Ben Arfa on a free would be the only option, but if you dont have any other suggestions...
