Yes. It is clear now that 2104 is shaping to be similar to 2011. Also it is clear that Nadal is incapable or maintaining exceptional form and winning multiple slams for two consecutive seasons.
So here is the pattern:
2009 - After having a great previous year ( 2008 ), Djokovic plays a sub-par season below expectations. Nadal misses big part of the season due to injury.
2012 - After having a great previous year ( 2011 ), Djokovic plays a sub-par season below expectations. Nadal misses big part of the season due to injury.
2010 - Djokovic plays another sub-par season below expectations, but at the end he wins the DC which gives him great confidence. Nadal has exceptional season after coming back from injury, winning everything everywhere.
2013 - Djokovic plays another sub-par season below expectations, but at the end he wins the DC which gives him great confidence. Nadal has exceptional season after coming back from injury, winning everything everywhere.
2011 - Djokovic 2.0 makes an appearance and has GOAT season. Nadal's level drops from previous exceptional season.
2014 - ?????
Be afraid, be very afraid - Djokovic 2.1 is coming to a tennis court near you in 2014.
