The striker, who joined Liverpool from Newcastle for £35 million in January 2011, linked up with Sam Allardyce's side last summer after being told he would be behind lone frontman Luis Suarez in the pecking order at Anfield.
Carroll initially struggled at Upton Park, not scoring his first goal until November, but has since notched six in his last 12 outings - although Rodgers admits the loan spell has not gone as well as first hoped.

"I suppose it's similar to last season, he showed that bit of form here at the end of last season and he's obviously shown that again at West Ham.
"The idea for Andy to go out [on loan] was to get games; he wanted to play, he didn't want to be sat here playing second fiddle to anyone and I commend that because some players are happy to maybe sit on the bench and not play.
"But he wanted to go out and play football. He's gone to West Ham, which is a great club, and under Sam Allardyce he's done very well. So we'll assess that at the end of the season and take it from there."
West Ham have expressed an interest in recruiting Carroll permanently, but the 24-year-old will snub a move to the Hammers this summer as he wants to stay and fight for his future on Merseyside.
