Age 25, in Russia?
Pass.
I think that an argument can be made that Janssen was the wrong signing because except for Kane, all our players who are being used as forwards are actually quick midfielders who shoot a lot (Son and Dele). Most of the striker targets we have been linked to in the past 2 years all fit that sort of profile too, as does Mane.
This is something many other clubs are also doing as well.
If so, signing a fast attacking midfielder who shoots a lot and has a frame big enough to fight with centrebacks is probably not a bad idea. I just don't think you're going to find that in a guy who is playing in Russia instead of a top league.
