The 30-year-old hadn’t featured for club or country after sustaining knee ligament damage in November, albeit the former Birmingham City man made his comeback against Southampton over three weeks ago.
Larsson was part of the Sweden squad that played against Turkey and the Czech Republic over the past week too, playing 45 minutes in both games.
The season starts now, says Larsson
Questions have been raised in Sweden over Larsson’s chances of going to France in the summer as he has only played once for Sunderland in four months.
Despite Larsson missing a large part of the season though, he has never thought his European Championship spot could be in jeopardy as he knew "he would come back in time," as he told Chronicle Live.
“I’m doing everything to get back to the form which will get me into the starting XI”, said Larsson.
Only eight games remain in the Premier League season, and with Jan Kirchhoff struggling to last 90 minutes, Larsson could still have a key role to play in Sunderland’s survival battle.
The North East side are in the relegation zone and will need most, if not all, of their players to be fit in a bid to avoid dropping into the Championship.
Larsson described himself as "fresh," insisting he "feels like the season starts now". He also believes when a player gets to this stage of a season it can "affect the body," as well as a player "mentally". However, Larsson says he feels the "opposite" and added that he has "plenty of energy".
Sweden manager Erik Hamren will undoubtedly be tracking Larsson’s progress as he looks to seal his place at the Euros.
“I’ve got seven or eight weeks before the season finishes and I can to the Euros feeling fresh”.
