Former Premier League referee Graham Poll believes it is a "great idea" to introduce the use of television replays in football because players are "more crafty and deceitful" than ever before.

However, he is unsure about the merits of giving managers the power to officially challenge refereeing decisions.

FIFA president Sepp Blatter on Monday spoke about his plans to give managers that power via a TV replay system, saying trials could take place in tournaments next year.

Blatter's proposal would see managers or coaches being allowed to make a number of challenges per half - only when there is a stop in play - if they disagreed with referee's decisions, with a final call being made by the official once replays had been studied on a monitor.

Regarding the use of video, Poll said: "It's a great idea.

"The game has speeded up. Players are more crafty and deceitful than they have ever been.

"Unfortunately, that is a fact of life, therefore referees do need help."

However, Poll feels managers could use Blatter's system "tactically" and that it might be best if they are not the ones to instigate a review.

"Everyone who watches a game on the television knows within seconds when a clear error has been made and the one guy that doesn't is the referee and that isn't fair," Poll said.

"I'm in favour of some technology. I would question whether we should give that power to the coaches or managers.

"They could use this tactically. You see tennis players sometimes who are looking for an extra 30-second breather will put an objection in knowing the ball has gone out.

"I think there should be other ways of reviewing situations.

"To my mind, there are plenty of good ex-referees who would be happy to sit there and review situations and help the referee."
