We have been interested in Sarr in the past but he is primarily a right sided forward and we now have a number of players who play in this position so I think this is unlikely.
Dennis tends to play on the left of a front 3 where we already have Zaha. He can play down the middle and is quick and skilful but from what I've seen of him he tends to be inconsistent.
I don't know much about the other two names linked, although Dolberg caught the eye in some international games a few years ago and I believe Vieira has worked with him previously.

I would think more likely to be Dieng.

I have read that Marseille want him out, which gives any buying club good room for settling on a fee.

Nail on the head !

Our existing strikers will come into their own IF we can find a midfield general. None of our existing midfielders can hold the ball - they just get rid of it quick, usually to a marked forward.

A ball holding player would give forwards time to find space. At the moment we seem to be relying on Andersen's long balls.

It always seemed to me our mis field last season was best when it included , Mc Arthur, and Gallagher. Now we cannot have both ,and McArthur , physically is not reliable any way. With Kouyate, allowed to go. And only his spot covered, we really need at least one more attack minded mid fielder, as we do need more fire power. If we could afford an out and out striker as well that’s a bonus, but at least one mid fielder with a goal threat is priority for me.

Hughes is probably about our best other option, which isn't saying much. He's ok - but when he came on against Arsenal his first involvement was to be easily bundled off the ball. He's a little lightweight.
There's Reidewald - who funnily enough looked better in pre season and never really lets us down. Obviously not great either though - a forgotten man.

Red and Blue Army!

We have signed Doucoure of course but just consider some of the other options in central midfield : Milivojevic, Riedewald, Schlupp, Hughes, McArthur (35 this year and injury prone).
Hardly players to strike the fear into the opposition !

Buy Sarr - he's just scored the goal of the season for Watford.
Pulled the ball down on his instep, turned and hit a shot from his own half.
Incredible piece of skill.

We were very reliant on experienced players playing in a way that was far from adventurous.We are now playing in a different manner.
Milivojevic does not contribute as he did, McArthur is now 35 and injury prone etc etc.
We have lost the energy and aggression of Gallagher in that midfield 'Engine room', Kouyate with that ability to break up the play, and of course as I have stated McArthur has his injury woes.
I really don't think that Hughes or Riedewald provide that PL quality and Clyne and Ward are hardly getting any younger.
Central strikers Mateta and Eduoard have averaged a goal every 5 games in the PL.
Patrick Vieira has commented that the squad needs more players.

A little disingenuous on your part Willo, if I may say so, as last seasons's stats suggest it's 1 in 3 when looked at in terms of minutes played. as opposed to games in which they have played some minutes.

One can examine statistics and interpret them in different ways drawing different conclusions.
