The 26-year-old was struck by a knee injury in February which forced him to watch the remainder of last season from the sidelines. While the striker is currently undergoing his rehabilitation, the Hammers are wary of bringing him back into the first-team fold before he is fully fit.
Despite West Ham co-chairman David Gold claming he may be available again from early September, the club are determined to see him undergo his own ‘pre-season’ training schedule to make sure that there are no recurrences of his previous injury problems.
Since signing for West Ham in a club-record £17.5 million deal from Liverpool in 2013, Carroll has struggled with a succession of injuries, the latest of which was a serious knee medial ligament injury he suffered against Southampton at the beginning of the year.
While new Irons manager Slaven Bilic has insisted that Carroll will remain an important member of the first-team squad under his stewardship, he is also determined to exercise caution before seeing him return to the playing field.
