Wolfsburg striker Obafemi Martins has slated his former Newcastle United teammates for not trying hard enough to beat the drop last season.
He said: "I was very happy when the move was completed because Wolfsburg are a team that is on the up with a good group of players.
"Plus, I didn't really want to play in the Championship after experiencing the Premier League."
Martins claimed many Magpies stars did not give their all to make sure the club avoided the drop and he revealed Newcastle's docs messed up a hernia op that hit his form.
He added: "In the last season I was injured and I had surgery. They did not do it right. Other players were injured as well and that's why we really went down.
"For me we also didn't try enough to avoid relegation."
