For me, Lukaku for 17 million pounds would be a no-brainer. Name the last teenager (just turned 20) who has scored 1 in 2 in the league.
17 in 35 for a poor West Brom team, as a 19 year-old.
11 in 22 for Everton, as a 20 year-old.
For me, he has so many attributes outside of scoring goals and is the perfect striker to play up top on his own. That said, in the WBA season, he linked up fantastically with Shane Long and Odemwingie (I think it was him) and helped lead them to their best season in a long time. He's definitely the kind of footballer who terrifies defenders when running at them, and he can bully even the toughest strikers in the league. In interviews, he seems like a smart, well-spoken kid, and he always puts a shift in. I've been a fan of him for the last few years, and I think if Chelsea would sell for around 20 mil, I would do it in a second.
He's looked a little worn out recently, and he's obviously been injured a bit this season, but that's mostly because he's been Everton's only real central striker for huge stretches of the season. I think he would be perfect here to learn from either/both Ade or Soldado.
The real question would whether to then sell Adebayor, which we possibly could to Turkey or something after his excellent season, and keep Kane in that third striker role. Or, we could keep all 3, which would create a pretty excellent strikeforce. I really want Soldado to stay for at least another season.
