Vlaar was out for a prolonged period with a troublesome calf problem but returned to the side for the final seventeen top-flight games.
He marshalled the defence brilliantly and even managed a couple of great goals - a piledriver in the 6-1 win over Sunderland and a Marco van Basten-esque volley in the 2-2 draw at Wigan on the final day.
Vlaar has had a few fitness issues this season too but when he has played, he's excelled.
Vlaar followed former Feyenoord team-mate Karim El Ahmadi and ex-AZ Alkmaar attacker Brett Holman to Villa Park when he became the club's fourth summer signing.
The commanding central defender became at cult hero for Feyenoord, who he helped achieve Champions League qualification with a second place finished in the Eredivisie in 2011-12.
Vlaar began his professional career at AZ Alkmaar, making his debut at the age of 20.
However, he struggled to hold down a regular first team spot at AZ and in 2006 he moved to Feyenoord.
His debut for the Rotterdam club came in January 2006.
Vlaar became a regular fixture in defence until the beginning of the 2008-09 season when he sustained medial collateral ligament and cruciate ligament injuries.
It meant the defender, known as Concrete Ron, was sidelines for two full seasons.
But it did not deter Vlaar, who made a strong comeback in 2009-10.
He formed a solid partnership with Brazilian central defender Andre Bahia.
Vlaar's leadership qualities really came to the fore in 2011-12 as he captained Feyenoord to second place in the Dutch top-flight and qualification for the following season's Champions League.
Vlaar made his first appearance for the Holland national team in October 2005 against the Czech Republic.
After overcoming his injury problems, he was recalled by coach Bert van Marwijk in 2010.
He also received a call-up for the Holland squad for Euro 2012.
