I see positives and negatives in replacing NTS with JM.

Positive, I agree Josh looked more comfortable on the ball than Topor did, but as others have said, I want to see this against A-League opposition.

What I think we have lost in this situation is a threat from corners and set pieces. Every time we had one last year I was looking for Topor to get his head on it. He was starting to deliver too. I haven't watched Mitchell that closely - does he offer that threat?

Also Topor was one of the quickest players we had. Sure he took a bit to get going, but he was quick. If Mitchell and Tiago are CB pairing, I believe their relative lack of pace will see us get caught out, particularly if we push a high line.

Personally, I think Regan and Mitchell will start the season. By seasons end, I expect Chapman and Regan to be the centre pairing.
