West Ham boss Allardyce: Nolan will benefit from Carroll arrival
He said: "I think what is important is the delight of everybody when Andy walked through the door today.
"I think it made us all feel that little bit better when you have got a £35million centre-forward walk through the door, whether you have got him on loan or not.
"He is a quality centre-forward and he is our number one and we can hopefully play to his strength and he can hopefully help us do what we want to do and that is by winning as many football matches as we can and hopefully we can provide him with the service to score lots and lots of goals.
"It brought excitement to Kevin Nolan's performance because Kevin can feed off Andy instinctively very, very well.
"Kevin could have probably had a hat-trick today because if he knows the ball is going to Andy, he knows he can go beyond and get into areas where Andy can find him."
