David Ginola: "To be successful in the game you need stability and it doesn't look very stable.
"I'm not saying it was the wrong decision on Tim Sherwood, I'm saying you can't be successful if you change managers every two or three years.
"You need stability first of all, the same staff working together with a bunch of players, year in year out, for at least two or three years, to make sure they will create this momentum a club needs to get success in the end, that's it.
"Tottenham did well with Harry Redknapp, then he went. They employed AVB, ok great, you have to take this.
"They spent 100 million last summer, sold Gareth Bale and in the end finish in roughly the same position.
"There was expectation, and fans were delighted to see the club spending money and pushing resources.
"It's a disappointment that Erik Lamela didn't play and Roberto Soldado didn't perform.
"Now they need the right person for at least the next three to five years, that's the most important thing, because success needs stability.
"So that's why I was a bit concerned when they got rid of Tim Sherwood, because he's a young manager, brand new, who had never done things before.
"But he's been working at the club for some time in the academy and knows the club well.
"He's got a good view; he had Les Ferdinand on one side and Steffen Freund on the other, so we're talking about a former Spurs player there.
"And I think at the end of the season, with Man United, with Giggs, Scholes, Phil Neville and all those guys, it looks right, it sounds right.
"But those guys need time, not for them to learn, but they need time to work with the players.
"Louis Van Gaal is at Man United, good, he's going to spend money on players, good, but he's expected to bring back results for the club, so it's a big task in front of him.
"And I think it's going to be a big task for the next Spurs manager, it's as simple as that."
