Sunderland manager Paolo Di Canio has vowed to sign more players despite already being the Premier League's busiest side this summer.
He wants to add a playmaker and left-sided defender to his 10 new players.
"If there is a chance then one or two more would be welcome and the club is working on this," Di Canio said.
"I'm happy up front and at the back and I'm happy in the middle, but we miss something. I hope in the next few days we are going to get something there."
Di Canio has increased competition in his Sunderland squad with his summer acquisitions but the Italian is not worried about having a large squad ahead of their Premier League opener against Fulham on Saturday.
The Black Cats boss has signed defenders Ondrej Celustka,Valentin Roberge and Modibo Diakite, while goalkeeper Vito Mannone, midfielders Cabral,Emanuele Giaccherini,David Moberg Karlsson and El-Hadji Ba, plus strikers Duncan Watmore and Jozy Altidore are the other new arrivals.
"I'm not worried about having a large squad because I want to have a chance to choose from a group of five rather than only two," he added.
"For me it's important to have players pushing for their place, and the other players have to maintain their place by doing well daily."
