There are a lot of reasons to feel like 2017 could be mistaken for 2007.
Roger Federer heading to the US Open later this month targeting a third grand slam title of the year.
The Swiss player likely to spend the remaining period of the year duelling for top spot in the rankings with arch-rival Rafael Nadal.
The latter scenario is not happening yet, given it is still Andy Murray sitting in the No 1 slot, but Federer v Nadal is coming.
Murray is sitting out the action at the Canadian Open this week as he continues to rest the hip injury which hampered him at Wimbledon.
With Novak Djokovic and Stan Wawrinka both ruled out for the rest of the year as they recover from injuries, the way is open for the Federer and Nadal renaissance to continue, this time for the No 1 ranking.
Nadal, 31, the world No 2, could go back there next Monday when the fresh list is published by the ATP.
He is only 285 behind Murray's rankings points total of 7,750, and reaching the semi-finals, which has a reward of 360 points, would put the Spaniard on top of the pile for the first time since June 2014.
Even if Federer, 35, the world No 3, is triumphant in Montreal for the first time since 2006, he cannot reach No 1 this week, given he is 1,205 behind Murray.
Murray did not play in Canada last year due to his Olympic commitments in Rio so he will not lose any ranking points despite being missing in action.
But business will pick up as the month goes on, and effectively it is going to come down to who has the stronger hard-court season between Federer and Nadal as to who will have the No 1 spot going into the closing months of the year.
Neither Nadal or Federer have many points to defend in the final four months of action this year, in Federer's case he has no points to his name to match, given he did not play again in 2016 after his semi-final loss to Milos Raonic at Wimbledon.
So, even if in some freak set of circumstances in which Federer did not win another match this year, he would at the very worst be on his current total of 6,545.
Nadal only has 405 points from 2016 still to defend, starting next week in Cincinnati where he was knocked out in the third round last year.
