I will disagree with 'Martinez made him'. He was already making a name for himself as such Chelsea paid around 20m for him. He needed game time so was shipped on loan to WBA and everyones ears pricked up at the amount of goals he was scoring in an average WBA team. Most of his appearances was as a sub also. He comes to goodison on loan as a fresh kid and scored aplenty. The next 2 seasons he dipped with consistency but still had all the attributes on show when up for it. Koeman comes in and takes him even further by adding the consistency and demanding more from him. Martinez did not make him but credit to him that he saw a goalscorer and got him here and since Martinezs departure he has stepped up another level because Koeman recognised his finishing ability so has made him the prime target for other players to seek and find. When Lukaku goes then Koeman will once again adapt to the strengths of the attacker he brings in and if not in the same mould as Lukaku will tweak the secondary striker and midfielders accordingly. We are not a one man team and I don't believe any team is. Its just playing to the strengths of what you have.
