@Bastian I wasn't going to respond but as you've asked, then signing him makes sense imo.
The likes of Bruno and Fred etc play with a lot of energy but they're easily bypassed by quick and agile players. Mount not only matches the aforementioned two for intensity but is also physically and athletically gifted hence he's stronger in defensive transition and tactically he's a superior player for a team that wants to sacrifice defensive stability for goals. It's why the likes of Liverpool and Arsenal want him, aswell as Tuchel rating him highly. All our forwards with the exception of Antony aren't very intelligent when it comes to defensive duties in defensive transition. And previously the likes of Pogba and Matic were also easily bypassed in midfield. So you can't control games without controlling both what you do in possession and also what you do out of possession. And what you do out of possession isn't very popular amongst some fans but it's absolutely imperative if one wants to implement a proactive attacking brand of football by playing the game in the opponent's half.
Also if we end up signing Harry Kane with him dropping deeper with Mount behind him, it makes more sense for a player with Mounts skillset to be behind him centrally, rather than Bruno imo. Mount is a proper systems player and hence a positional play coach like Tuchel was able to get his ideas across quickly to the player. Mount can also be used as a pressing trigger and is technically good, aswell as tactically clever.
And I hope we can get the deals done quickly because for me the most important positions to target to dominate games is a keeper, CM and RB. And those three positions are key to exerting control in possession and play through the press and raise the defensive line.
