Sam Allardyce outlines what he feels Newcastle will need to guarantee to persuade Rafael Benitez to stay

The Sunderland manager believes Benitez will not settle for the way the Magpies approach transfers and will want more control.

Sunderland manager Sam Allardyce has told Sky Sports that Newcastle United will need to stop relying on stats-based analysis from above the dugout in the transfer market and instead give Rafael Benitez control if they are to persuade him to stay at St. James' Park.

Much has been made of where Benitez's future lies this summer after his valiant attempt to keep the Magpies in the Premier League was ultimately unsuccessful.

After failing to win any of his first four games in charge, the Spanish boss led the Tynesiders to a six-match unbeaten run to end the season, finishing with a 5-1 thrashing of previous title challengers Tottenham Hotspur, and the club's supporters unsurprisingly appear united in their desire to see him continue.

One of the factors which could be decisive in Benitez's decision is clarity over his role with respect to transfers, with Newcatsle having favoured a stats-based approach from the boardroom in finding new signings rather than handing the manager free rein.

Allardyce, whose Sunderland side sent down their rivals with a 3-0 win over Everton on Wednesday night, believes that the Magpies would have to offer Benitez assurances that he could be in control of transfers if they hope to convince him to stay at the club.

The Black Cats boss told Sky Sports: "What's interesting for me, and the big thing for Newcastle at the moment, is that Rafa hasn't made his mind up. He did make a difference obviously, he did what he had to and tightened the defence up straight away.

"He wants to be more in control of the ins and outs of players. As a manager there tends to be a lot of structuring above in ownership these days, where a lot of people come together. I'm a big analysis man, as you know, but analysis doesn't find you a good player. It gives you the stats, but you can't run on them.

"I get a bit worried about the choices being made in the way they become stats-based. But unless you've got the scouts who go and look at these players, then you know whether the signings are going to be right or wrong for you."

After the superb win over Spurs in Sunday's final fixture, Benitez and the club must now decide the manager's future, with Magpies supporters petitioning for the Spaniard to remain at St. James' Park.

As Allardyce suggests, with Benitez a big managerial name it is likely Mike Ashley, Lee Charnley and the rest of the board would have to compromise their own authority if they wish to keep the former Liverpool, Chelsea, and Real Madrid boss.
