Sunderland football chief Lee Congerton says they're aiming to avoid another summer of major squad changes.
The Black Cats made 14 signings during the last closed-season and only just escaped relegation.
Asked if he envisaged a similar influx, Congerton told BBC Sport: "I want to say no, but when we look at the team ourselves...
"I'm sure any fan can say we need a left-back, we probably need a centre-half, we probably need some midfield players, we probably need to replace Fabio (Borini), maybe a centre-forward, so all of a sudden, the numbers are going up into double figures again, and that's the last thing I want, and Gus (Poyet) as well.
"But we need to improve the quality. The starting 11 is very important, we need to have a squad.
"But first of all, we need to have a starting 11 that can be competitive week in, week out in the Premier League, so we do need more players.
"But for me, it's not so much about the quantity, it's also about the quality. I don't want to sign players just for the sake of it."
