He's like a brainless Fernandinho with much worse decision making and tactical awareness. That's at least what he's looked like at Spurs, I have no idea what he was like at Corinthians. Tbf, the way Tottenham have been playing it's really hard for a CM to shine, but even taking that into consideration he's been in really poor form this season. So, I really can't see this happening because you just don't come to a club like Chelsea after having a bad season.
