We currently need a striker and a forward who can play right across the front 3.
So we need 2 for sure in the next week. If Gordon goes we need 3 in. 3 forward thinking players in a week.
We can't just be pinning our hopes on, let's say a Broja, DCLs fitness issues have been for over a year now. What happens if Broja got injured? We literally have no depth as it is, so if Gordon goes we need another.
I'm not talking about about the likes of a 1 goal a season, 1 assist Mcneil type either. We need 3 forwards capable of adding 8-10 each a season and +5 assists.
I don't think we really do need another one if Gordon goes mate, or at least not one of the exact same types.
We need, as you say, a striker and a quality, versatile attacker/wide forward.
Then I'd say the priority is also defensive mid (Gueye, but we should be able to do that regardless of Gordon) and a creative player. Maybe that player does play wide but I'm thinking more from midfield. I don't know much about Kudus but given we are/were in for him it suggests they want someone who can help progress the ball centrally and has quality to deliver the final pass too.
Four players in. IMO that's fine, as long as that balance is covered: defensive mid, creative player, versatile attacker (this should be where a decent chunk of the money goes IMO) and a striker (I think it'll be Broja).
