The manager has also confirmed that talks have been held over Yann M'Vila and DeAndre Yedlin.
Sunderland manager David Moyes has told the Chronicle that it is obvious they need a new right back, centre back and centre forward this summer.
Moyes was confirmed as the new Black Cats manager last month after Sam Allardyce left to take charge of England.
He is keen to bring new signings to the club as soon as possible as he looks to build a side capable of avoiding yet another relegation battle.

So far no new players have arrived at the club, with Allardyce openly admitting his frustration at the lack of movement before he departed.
They need several signings just to increase their squad to a competitive number, and Moyes says it is obvious which three areas should be a priority.
“It’s obvious we need a new right-back, centre-half and a centre-forward, and that’s before we even start to think about anything else,” he told the Chronicle.
“They are merely needed as a given. We’ve got to get those players in right away, just make it work.”

The Sunderland boss has also admitted that talks have already been held about potentially bringing Yann M’Vila and DeAndre Yedlin back to the club.
Both players were big hits while on loan at the club last season, and the club was keen to bring them back while Allardyce was in charge.
And it appears that has not changed under Moyes, who says that both players have been discussed in his transfer negotiations.
“Both M’Vila and Yedlin made decent impacts,” he added.
“They are players who we have talked about in the last week a lot, and we have spoken to people about them."
