Cole delighted Carroll staying with West Ham
The Geordie signed permanently for the Hammers from Liverpool last month.
Cole told whufc.com: "It is a boost for the club and shows where we are going. Andy Carroll is a young, England centre-forward and clubs do not usually sell them. He's a big talent. He did a good job and we just want him to get fit and come back because he is a big part of our team."
