Sunderland manager Paolo Di Canio is targeting six or seven players as he prepares for a recruitment drive.
Hearts assistant manager Edgaras Jankauskas is to leave Tynecastle just a year after returning to Edinburgh.
Bologna have announced that coach Stefano Pioli has extended his contract with the club until the end of the 2014 season.
Pioli guided the Rossoblu to a ninth-place finish in Serie A this season and had been linked with the vacant manager's job at Lazio following Edy Reja's resignation at the Stadio Olimpico.
But Pioli, who was sacked by Palermo in pre-season, has agreed to extend his stay by a further year with the Dall'Ara outfit after agreeing a one-and-a-half year deal in October.
"I've read the reports, but I've had no contact with them (Lazio) or any other clubs," the 46-year-old told Tele Radio Stereo.
"I can exclude the possibility that I will be leaving Bologna. My staff and I want to give a bit of consistency to the work we have done this year.
"It's normal that there are rumours, but I am happy at Bologna who have put me in the best situation to work."
