Tottenham manager Harry Redknapp believes his Arsenal contemporary Arsene Wenger is wrong not to consider employing a specialised defensive coach to help his side's current troubles reports espn.co.uk.
After a series of uninspiring displays this season which have highlighted the club's defensive frailties, it was perhaps surprising that Wenger was so opposed to suggestions he could benefit from adding the likes of Tony Adams or Martin Keown to his backroom staff.
But the Spurs boss is convinced it is only a matter of time before football follows in the footsteps of the NFL in America - where team's employ coaches for every specialist position, and said he would welcome the opportunity to add to his coaches at White Hart Lane.
"Arsene is entitled to his own opinion but I think it won't be long before we go down the American football route and have specialised coaches for every position in the team," Redknapp told The Sun.
"I played out in America and got hooked on the NFL while there. They are years ahead of us in terms of coaching. They have quarterback coaches, wide receiver coaches, a coach for almost every conceivable aspect of the game.
"I see nothing wrong with it. It will only improve the players and, as a result, improve the end product which is designed to entertain the fans."
Arsenal have already shipped a worrying fourteen goals in their opening five Barclays Premier League games this term, and Wenger's stubborn stance could ultimately have a negative affect on his Gunners squad, as he looks to end the club's barren run of six years without a trophy at the Emirates Stadium.
Unlike Arsenal, Tottenham are not under quite as much scrutiny to land some silverware this season, but Redknapp will be hoping Spurs can at least secure a top-four spot and return the club to the UEFA Champions League next season.
"Sometimes you have a group of about 20 players and you end up trying to do something that caters for them all and you come away afterwards and wonder what you have actually achieved," he continued. "What we must do is reassess what we mean by 'coaching'.
"After all, we have expert dieticians, expert medics and expert fitness guys. Why not expert trainers to get the best out of your players?"
