Christopher Samba has admitted that he was not ready for the rigours of the Premier League after he signed with QPR in January.
But after the Hoops were consigned to the Championship on Sunday, Samba admitted he wasn't up to it.
"From my personal point of view, I don't think I was well prepared to come back to the Premier League," he told Sky Sports News.
"It is the hardest league and you need to be fully fit and really ready to compete.
"We had many chances to get out of it and didn't take them, but that is football."
He added on his QPR future: "I don't know. I am not the only one who makes these decisions. I have failed to help the team and I only know that I will be much stronger next season."
