乔纳森-戴维：我可以踢任何位置；一直在训练后进行加练（乔纳森-戴维：位置不设限，训练后我总会加练）

Here are two clean English renderings:

• Natural: “Jonathan David: I can play anywhere; I’ve been putting in extra work after training.”
• More idiomatic: “Jonathan David: I can play anywhere on the pitch; I always stay after training for extra work.”
