Nolan unsure if Carroll wants West Ham stay
Nolan understands that Carroll's own ambitions will be a bit factor in his final decision.
"Andy is a clever lad, he knows he has got to play football," said Nolan. "If he gets offered someone who are in the Champions League or the Europa League, then he has got to make the decision.
"I know he has enjoyed his time here, you can see that on the pitch, he gets on well with all the lads, so we will see what happens."
