Sidwell told the Reading Chronicle: “I had a long chat with the gaffer and I said it was fine with me whatever he decided.
“He was on Sky Sports last week and he seems resigned to the fact I’m leaving this summer. But I’m keeping my options open.
“I know the season is beginning to wind down now, but I am not going to make any rash decisions.
“It is an important part of my career and I will speak to the people closest to me about what is the right decision.
“But I will wait until the very end of the season before I make a final one.”
Sidwell has been linked with Manchester United, Chelsea, Aston Villa, Everton, Middlesbrough and Manchester City.
