Sir Alex Ferguson has admitted he will be wary of Louis Saha starring against his old club on Sunday, as Manchester United prepare for a tough match up with Tottenham.

Saha played for the Red Devils between 2004-2008, before making the move to Everton for an undisclosed fee.

And as the former United striker prepares to face his old club for the first time in a Tottenham shirt, Ferguson admits he has a better understanding than most over Saha's abilities on the pitch.

"I don't know the circumstances behind Louis Saha's transfer but Everton were happy to let him go," Ferguson told Inside United.

"And then he goes to Spurs and scores two goals [against Newcastle]. That's typical of Louis. He's got tremendous talent, he just doesn't play enough.

"He is a handful, no doubt about that. He's got two great feet, he's quick, he's got a good spring in the air. There's no doubt he is a handful. They've got a fantastic squad, and a goal threat throughout the team. Gareth Bale contributes, Rafael van der Vaart, [Jermain] Defoe, [Emmanuel] Adebayor. They've got goals in their team."

Saha endured an up and down time at Everton before his January move to Tottenham, with the 33 year old suffering from ongoing injuries.

But his goals against Newcastle, in a match Spurs won 5-0, were a testament to his skills, which Ferguson is well aware of.

For both Tottenham and United, this will be a do or die match up, with Spurs hoping to keep their edge over fourth and fifth placed Arsenal and Chelsea, and the Red Devils aiming to keep the pressure on title leaders Manchester City.

Meanwhile, Saha revealed this week that Ferguson was known for his hair dryer moments for a reason, with the hitman recalling one particular moment where he was given a shout down by the United legend for his performance on the pitch.

Saha had scored twice against Everton, and the side were up 3-0 at half time, but Ferguson wasn't happy, and the France international eventually understood why.

"When I headed towards the changing room, I was feeling proud. As soon as I sat down, I was woken up in a violent way - Sir Alex Ferguson rendered me deaf," Saha told The Sun.

"I was surprised but yes, it was me he was yelling and screaming at.

"He was going mad and I quickly understood why - he was unhappy because we came in with only a three-goal lead when we should have wrapped the game up.

"He was furious about my missed chances and reminded me that this is the very top level. Wow. I woke up even more sharply when 45 minutes later Everton had come back to 3-3. Goodison Park was on fire.

"Only Ruud van Nistelrooy helped me escape the nightmare - with a stoppage-time goal."
