Speaking to the media, Slot said: "I talk to most players, not on a daily basis, but a lot. If there are circumstances why I should talk to them, you talk a bit more often to them. It's clear with Trent's situation that those circumstances are there for me to talk to him.
"I am talking to him as a human being. That, combined with winning something together, creates a different bond to the one the fans have with him. When we started pre-season, he was in my office quite a lot as well for similar reasons to what Mo [Salah] has said previously.
"He is going to leave either way, so why not say it? Maybe it is a first gift I can give to Xabi Alonso! I wasn't completely happy with every minute of how he was on the training ground. In certain moments, I felt he could do a bit more, to say it mildly. That is what we talked about.
"I told him, 'You are a much better defender than people tell you, but you don't show it all the time.' I said, 'If you are at it and concentrated, there are not many players who can go around you'. Because he is fast, agile, has a great mentality, but it is about showing that every single game."
