You want to keep forcing these fights in Feudal Age, try and get some damage, maybe slowly level up Jeanne d'Arc. It's just going to be the classic composition: spamming Knight Archer, just keeping it in Feudal, trying fighting him for as long as possible.

Delhi tends to have a really good match up against Jeanne d'Arc in general because the Ghazi raiders get bonus damage against heavy cavalry, which is a great extra when it comes to fighting knights.

JD has reigned supreme for quite a while. The Gazi raiders, they have maces cuz they do a little bit of bonus damage to armored units, but pound for pound a knight just feels a lot better when it hits into a Gazi and especially with time JD will have that discount on them as well.

Ghazi Raiders run faster than knights, so having a forward gold is difficult to handle.

Ghazi Raiders do outrun Knights and they have some nice bonus damage, so if you detach small groups of knights and you're trying to hit the Eco you could easily get yourself cleaned up.
