I'd be very surprised if we get another top striker. I think we'll need to uncover a gem to cover for Kane. Not much chance a top player who wants regular first team football joins a club with Kane, Son, Alli, Lamela, Moura and Eriksen. I can see him joining a club who is in need of a first teamer. Not to say he wouldn't get in our team but you would prefer your chances at a club without that much competition like us.
You need the 2 sides to agree before the player and agent even get involved though. This sounds like a long way off for this window. Maybe one to revisit in the summer. He's worth trying for at least.
The thing is, we do have space for another top WF/SS/Striker like Werner.
Llorente is basically retiring and can't play every week anyway.
Son isn't a striker.
Lamela and Moura are upgradable.
Eriksen is likely leaving in the summer.
We absolutely need to sign another forward. We either be proactive and sign Werner or another striker now, which also helps us achieve our sporting goals this season, or we wait until Eriksen leaves for Madrid in the summer and every club knows we have loads of money, plus every other top club are scouring the market which makes it more competitive, plus we end up in the Europa league because we didn't sign a striker in January.
