Frank: Wirtz is as good a new player as Harvey Simmons, both of whom still need to adapt to the new league

. I think Brennan can play left and right, I've said that before. Of course Kudus plays well on the right, for example. And then on the left, I think Odo Bell did a good job as well. So there's just a bit of competition. Brennan just needs to stay in shape and he'll get a chance to play. "

Have you ever considered switching to three central defenders?

Frank: "As I said before, for me, the key is not the system, but the guiding principle. I think now I still think 4-2-3-1 is the first choice, it depends on the type of opponent. Like I said, if we had won 1-0 against Villa, which we could have easily done, I would have been satisfied. So I think the overall performance was good, very competitive, and I'm happy with that. I know we need to add some layers and we're working on that. "
