Andy Murray ended the year as world No 1 after a dominant victory over Novak Djokovic in the ATP World Tour Finals decider in London on Sunday. But the week produced more storylines than just the race to be the best player on the planet.Here, we pick out the key conclusions from the O2… World Tour Finals: The verdict Marcus Buckland, Barry Cowan, Annabel Croft, Peter Fleming, Mark Petchey and others Murray can dominateSundays final was not simply a match to decide who would win the title and end the year as world No 1. It was a glimpse into the sports immediate future and a test of whether Murray is capable of staying top of the rankings in the coming years. Murray spoke to Marcus Buckland, Annabel Croft and Gred Rusedski after beating Djokovic After several months of patchy form, Djokovic had looked back to his imperious best on his route to the final and although his level dropped considerably over the following one hour and 42 minutes, the ruthless manner in which Murray dispatched him 6-3 6-4 suggested a tennis axis has shifted.Murray was fatigued and under immense pressure, yet he outplayed Djokovic to such an extent that it seemed he has not only met the standard required to be No 1, but raised it. A period of domination potentially beckons.Djokovic still out of sorts, but will be backDjokovics rapid and clinical progression to the final was so impressive that many analysts tipped him to beat Murray and snatch back the world No 1 ranking, but those predictions fell flat in a nervous and error-strewn performance that the Serb himself described as very poor. Highlights of Murray v Djokovic Djokovic held a 24-10 head-to-head record over Murray going into the match and had beaten him in two Grand Slam finals this year, so such an abject display suggested he is not yet over his struggles of the past five months.However, Djokovic remains one of the fiercest competitors currently active in any sport and is close enough to Murray in the world rankings to make a fightback in 2017 more than feasible.Raonic a potential future No 1Murray may have taken the title and the acclaim, but it shouldnt be forgotten how close he came to being knocked out in the semi-finals, when he fell a set and a break down to Milos Raonic and then had to save a match point in the third-set tie break. Milos Raonic edged Murray in this superb 20-shot rally in the semi-final Raonic also gave Djokovic a scare in the group stages, losing in two tie breaks, and although his record at the tournament was only two wins and two defeats, his results were good enough to lift him to No 3 in the world.Of more significance, however, were the pedigree of his performances. His serving and groundstrokes were unplayable at times, and if he can just become more adept at moving forward to the net, he could become as big a threat to Murrays No 1 ranking as Djokovic.Thiem a potential Grand Slam winnerAnother player who impressed at the O2 was 23-year-old Austrian Dominic Thiem, who was effectively a wildcard entry taking the place of the injured Rafael Nadal. Dominic Thiem steps up to the SkyPad to talk through his match against Gael Monfils He defeated Gael Monfils in three sets, took a set off Djokovic and forced Raonic to a tie break in an impressive weeks work that hinted he is the most exciting young player in the sport and could mature into a Grand Slam winner.Long way back for Roger and RafaThey are former No 1s who together once dominated the sport and later formed part of the Big Four with Murray and Djokovic, but Nadal and Roger Federer now find themselves down in ninth and 16th in world rankings respectively. Rafael Nadal is now world No 9 Their fall has been largely due to injury, but with Murray having raised his level, the likes of Raonic coming through and Stan Wawrinka now regularly winning Slams, the road to returning to the top four - let alone world No 1 - looks a long and tough one.Upgrade to Sky Sports now and get 12 months half price.

They have management committed to its plan and multiple superstars (with potentially more to come) to make that plan work at a high level of effectiveness.Whats goodThe Astros have talent in good amounts. This is not the teardown team of a few years ago. The highlight for fans is the 36th-ranked roster: Carlos Correa and Jose Altuve are the Astros version of Cubs stars Kris Bryant and Anthony Rizzo. In 2017, you might find yourself arguing which of Correa or Altuve is more MVP-worthy. After an awful start, Alex Bregman showed flashes of greatness in making the transition to third base. He was Keith Laws No. 1 midseason prospect, so theres a lot of hope and anticipation regarding his, and thus the Astros, future.Whats badAfter a postseason berth in 2015, theere were high hopes for 2016, but this seasons squad didnt quite live up to expectations (and couldnt help a 73rd-ranked title track, one of Houstons poorest showings).dddddddddddd Dallas Keuchel and Collin McHugh were unable to replicate their 2015 performances, and the teams best pitcher, Lance McCullers, made it through only 14 starts. Starting pitching would figure to be a priority moving forward. Fans also clearly expect more from manager A.J. Hinch, who fell 19 spots to 70th overall.Whats newWhats new is that we live in a world in which the Astros are highly regarded -- and relevant. After back-to-back 80-plus-win seasons (the first time in a decade that has happened), the team bumped up 26 spots in bang for the buck, which indicates that the community is supportive and the days of 0.0 TV ratings are a thing of the past. Theres nothing about the Astros that screams championship (besides Correa and Altuve), but there isnt anything that makes you wonder what the heck theyre doing, either.Next: Los Angeles Dodgers?| Full rankings ' ' '
