Allardyce praises Carroll impact

West Ham United manager Sam Allardyce praises the immediate impact of loan striker Andy Carroll after his debut against Fulham at Upton Park.

The 23-year old played a key role in two of the goals as the Hammers thrashed Fulham 3-0, with all three goals in the first half.

However, Allardyce says Carroll will not be in the England squad for the World Cup qualifiers, after he limped off with a tight hamstring.
