It's a tricky one. You could argue Solanke deserves a chance under a new manager to show what he can do, (although he's not exactly set the world on fire so far under De Zerbi), but Richarlison's still got the much higher goal threat (when he's fit enough to play, which is another issue).
Out of the two I prefer Richarlison, but I don't think either of them are good enough for us, sadly.
Bringing in two new front man at the same time, is a huge risk though, especially given Spurs record with buying strikers over the years, and the general dearth of top talent in the position at the moment.
It's a dilemma for sure. There's some tough decisions to be made in the summer in regards to our recruitment. Just hope the guys we've got in charge are up to the job...

Oh, FFS!
