Chelsea chief Michael Emenalo stands by their use of the loan system.
The likes of Thibaut Courtois, Oriol Romeu, Wallace, Victor Moses and Romelu Lukaku have all left Stamford Bridge on loan moves over the course of the summer but Emenalo reckons it will benefit the Blues in the future.
"The loan process at Chelsea has become very professional and a good deal of thought has gone into it," he told chelseafc.com.
"We don't send players out because we are trying to recover some money, we send them because we want them to play and develop and we want to monitor them.
"We have a system in place, headed by me and with Eddie Newton supported by [head of player welfare] Kevin Campello, that means we keep a close eye on them and the manager knows exactly what is happening at all times."
