Career
He is regarded by fans as a "fearless defensive midfielder who is very capable in the air as well as with his feet". Often nicknamed "Il Grande Pontus" (Literally translated "The Big Pontus") by some of his fans, his physique is perhaps one of the reasons he has gained such a nickname. After playing for local club Herrljunga Saskatchewan, he joined the youth team of IFK Göteborg in 2004, before being promoted to the senior team in 2005.
He quickly made a name for himself with his hard tackles, fighting spirit and generally fearless playing style.
When Håkan Mild retired after the 2005 season, Wernbloom secured a place in the starting line-up. However, during the following season he struggled to retain his place as the club changed its playing style under new management.
When striker Marcus Berg left to play for Football Club Groningen in the summer of 2007, Wernbloom switched to forward and was able to be a starter once again. In April 2009, he signed a contract with Dutch club Arizona. He made his Eredivisie debut against Heracles Almelo on 2 August 2009 and scored his first goal in a 3–3 draw away to VVV on 21 February 2010.
Wernbloom scored a goal in both play-off round legs against Kazakh side Football Club Aktobe, helping his team to qualify for the group stage of the 2010-2011 Union of European Football Associations Europa League.
In January 2012, Wernbloom left Arizona for signing a long-term contract with the Russian top club CSKA Moscow. Plagued by injuries, Wernbloom was plunged into the deep end against a highly favored Real Madrid side in the knockout stages of the Champions League. He debuted for the Sweden under-21 side in 2006, scoring a goal in the 12th minute of the match.
On 7 January 2007, he was picked for the Swedish national team"s January Tour in South America, and he made his debut on 18 January against Ecuador.
