Harry Redknapp was impressed with Sandro's debut in Tuesday night's Carling Cup third round loss against Arsenal.
The Brazilian midfielder - making his debut alongside Stipe Pletikosa and young defender Steven Caulker - couldn't have asked for a tougher baptism in English football than the North London derby.
But despite suffering from cramp in the second half, he stuck to his task for 96 of a tough 120 minutes at the Lane.
Starting in central midfield, Sandro covered every blade of grass against a strong Gunners midfield including the likes of Tomas Rosicky, Denilson and Jack Wilshere.
"It was his first game in England, the pace of the game would have been different and he did a great job, he worked really hard," said Harry.
"I like him, he looks a good player. He's full of energy and gets around the pitch. I think he'll be a good player for us."
It's always difficult to talk about positives after defeat against the Gunners but Harry was also happy with two Academy trainees - Jake Livermore, making his first start and debutant Caulker, still just 18.
"For a start, no-one wants to lose, especially against Arsenal," said Harry.
"It was a chance to look at some of the lads. Young Steven Caulker at centre-half did a good job and he'll learn a lot from the game. It was his first game at anywhere near this level and a great experience for him.
"Jake will do well here. I took him off at half-time, he had a booking, but I think he'll be a good player.
"He gives everything. I think eventually he'll be a good player here and play for Tottenham many times."
