Mauricio Pochettino's imminent arrival at Chelsea is an interesting one. Yes, he built a great side at Tottenham but he didn't win anything and although I'm sure he'll make Chelsea contenders again, I don't think he'll land any silverware for them because I don't think he's a winner, he just gives you a whiff of winning.
It's one thing winning in France with Paris Saint-Germain — if you don't win something there then for God's sake what are you doing — but if you want to go to Chelsea you'd better make damn sure you're a winner and I'm not sure he is.
