Sunderland chief Margaret Byrne insists manager Martin O'Neill will not to sell this summer.

Byrne says its just about spending money wisely.

"No, we don't have to sell players in the summer, definitely not, it is just about doing smarter deals," said Byrne. "You don't want to sell players. We sold Jordan (Henderson) at what was the right time for us, and the players we brought in from selling Jordan have had a heck of a lot of influence on the team.

"We brought in Seb Larsson on a free, Craig Gardner in for £5million, Wes Brown in for £1 million and John O'Shea was £5million. Selling at the right time and getting players in at the right time is key.

"Ultimately it is the manager's prerogative. He might see raw talent in someone."
