Paolo Di Canio: "It is clear that we have to bring in players over the summer - half-a-dozen, maybe more.
"We finished near the relegation zone and so it is obvious that we need to make changes to make sure that we are not in this situation next season.
"But at the same time we already have some quality players here, and I want them to stay.
"I want to build something here at Sunderland and take the club forward - that is my mission. So the last thing I want to do is to let any of our quality players leave.
"Simon Mignolet is a top class goalkeeper. He's very important to us."
