Former Newcastle United goalkeeper Steve Harper has told Sky Sports that he believes Sam Allardyce will make big changes at Sunderland.
Harper, 40, is a free agent having been released by Hull City over the summer, but he will be best known for his time with Sunderland's biggest rivals Newcastle.
With almost 200 appearances for the Magpies, Harper was a long-serving stalwart for Newcastle, and he played under Allardyce during the 2007/08 season.
60-year-old Allardyce has made his return to management having left West Ham on the final day of last season, taking the reins at Sunderland on Friday.
Allardyce played for the Black Cats during the 1980's, and is now charged with task of leading the club away from relegation trouble, following the departure of Dick Advocaat last week.
Now, Harper has told Sky Sports that Allardyce is a 'cracking appointment' for Sunderland, and predicted that Allardyce will make big changes at the Stadium of Light, just as he did upon his arrival at St. James's Park eight years ago.
"He will certainly make big changes in and around the place, he did that at Newcastle," said Harper. "He will give the players exposure to all areas, not just on the pitch, off the pitch to get the best out of themselves.
"He'll organise them, they will be well drilled, they'll be a threat from set pieces and what he will do is give them a platform to get the results and, by having that well organised platform, give them the opportunity to go out and play from there. I think it is a cracking appointment," he added.
Allardyce can't overhaul his squad outside of the transfer window, but January may be an interesting time for Sunderland fans, with 'Big Sam' no doubt looking to mould his own squad having penned his deal with the Black Cats.
