Well they are only at 7/2 to win all 4 now, which incidentally is therefore about 4 times as likely as Spurs getting Top 4.
It is still 5 head to head matches they have to come through Chelsea, Tottenham, PSG and then either Leicester/Southampton and Real Madrid/Chelsea again
Still doubtful they will win all, if they do it has to rate up as one of the biggest achievements in football history, maybe not Leicester winning the Premier League, Greece winning the Euro Nations, Steaua Bucharest winning the European Cup or Montpelier winning the French League big, but a massive achievement nonetheless.
