The Latics boss hopes to strengthen the team’s central defence and midfield to increase cover and competition.
He said: “"Our squad is still very light, we've made some quality signings, in my opinion we need five or six more to be competitive in every game.
"With our depth, I think people can see at the top end of the pitch we look okay, we've plenty of competition for places and in the wide areas.
"It's the central areas - central defence, cover at the back, centre midfield. In a normal campaign it's testing and taxing.
"Throw Covid in there as well, you are going to need depth in numbers otherwise once the window's closed, you'll be found wanting.
"We're going to need more if we are to be competitive in every game."
