Play midfielder with higher defense over defender who has lower defense?

[Pingu Noot]

I have a very important game that I cant lose and i'm planning to use 6-3-1. The problem is I only have 5 good defenders, the sixth defender is 90 defense rated and I have a midfielder who has a 94 defense rated player. Should I use the defender or midfielder?

Thanks
