I think the objective view of our attack is your coutinho, salah, mane front 3 is equal in strength to our Alli, Eriksen, Son one.
I'm not sure that is the objective view mate, I think that may well be the very definition of a subjective view...
That said, I'd take Kane over Firmino any day of the week. I love our Bobby but Kane is a tremendous striker, even if I'm not sure that he's currently the best striker in world football, or whatever it was you said.
Hopefully it'll be a good game tomorrow. We're a good team, you're a good team, and neither of our managers is a bus-parking Mourinho type so there should be a few moments of entertainment, at the very least.
