Andy will take over the mantle as world no.1 from start of 2017 season, if not before at ATP Finals in November....He totally deserves the to be at the top of the pile as he's been playing the best and most consistent tennis out of the top 10 all season long. Wimbledon title, Olympic title and finalist at both Aussie and French Open, semis in US Open and a few 500 & 1000 Master Series titles to boot. The gap in points was 8000+ and now it's 1400!
