Keep in mind that Obi Mikel and Ramires commonly start for Chelsea. Mereiles is not going to be an impact sub behind those two. If he is, that's ridiculous, because Ramires in particular is not close to Mereiles and Obi Mikel is just a go-to player when Essien isn't fit/playing well. Creativity was always the word being used for what Chelsea lacked, and with Mereiles and Mata, they've two players with more creativity than any of their initial midfielders. As for strikers, if you think you can say Torres won't come good, you're optimistic or bitter. If you think Anelka and Drogba aren't capable of 15 to 20 goals, I'd disagree. Lukaku and Sturridge are incredibly good for their age and I expect them both to be PL stalwarts for many years to come (have you seen Lukaku? It's insane when you think about him being so much bigger than most seasoned central defenders... and I'm talking about when he was just 16).
