Leighton Baines expects Everton boss David Moyes to be active in this month's transfer market.
"The manager and his staff work hard at looking for new people," said the England defender.
"They scout the world and even if it's only loans, they try and do something as they have in the past.
"It tides you over and freshens things up, but it's a tough job for the manager because the funds aren't always there to do the business he'd like to.
"You can see what we're doing, at least matching a team like Chelsea without key players.
"It's when we're missing three or four that it affects us. We can cover one or two because we have a little strength in depth, but any more and we feel it.
