There are loads.Box-to-box midfielders is a position you need to train somebody for. There are very little box-to-box midfielders in the game (in general). Try to find a young talented creative midfielder with high work rate, passing and teamwork. He also needs a few points of strength. If he is very young and has atleast 12 str, he will be able to reach a nice amount.
5th: Lucas Romero
They are all strong and can pass a ball. It will cost you about 10mil to find a great box-to-box midfielder. Obiang is a beast. He is not fast, but he doesn't need to be. He still gets where he needs to be.
