Arsenal fan Piers Morgan:, external Don't understand Pochettino's decision - why would he trade down?

Comedy actor Stephen Mangan:, external Welcome Mauricio Pochettino! I hope I get to see one of his Spurs teams play but I can't get to WHL til November so it's probably 50/50.

Back to Spurs? Mauricio Pochettino is the ninth manager to have been appointed by chairman Daniel Levy since he took over as Spurs chief in 2001.

Believe it or not his last man, Tim Sherwood, has the best win ratio of any White Hart Lane boss since the Premier League began - 59.1%.

Who's at the bottom? Jacques Santini with 27.3% - but then he was only in charge for 11 games.

On a more serious issue, there have been further anti-World Cup protests in Brazil. These have happened in the capital Brasilia.

Police fired tear gas at anti-World Cup and indigenous demonstrators. Stones were hurled at security forces as hundreds of protesters tried to reach the National Stadium - where the tournament trophy is on display.

A group of indigenous people who were demanding land rights at Congress eventually joined the protest.

There's an ODI cricket match between England and Sri Lanka set to start at 14:00 BST at Old Trafford.

Looking out of the work window, about a mile or so from the ground, I can see the rain is spitting down. The forecast is for it to rain until 1600 BST, before it starts raining again at about 20:00 BST.

And what of the view from the south coast? Here's former Southampton boss Dave Merrington:

"There's been a lot of anxiety in the dressing room and among the fans. There's been an uncertainty among the players for weeks now and I just think the board have allowed things to drift on and still expect the fans to renew their season tickets. The fans probably at the moment are not very happy.

"I'd like to see them give the job to one of our up and coming managers in this country. You've got David Moyes who has left Manchester United. People will say 'oh well he didn't do it at United', but he did a great job at Everton. You've got the guy who left Cardiff.

"You've got a number of people in the country who have strong credentials to take the job on but you never know. It's a foreign board that we have and it could be that they'll go again for a foreign manager. I just hope that they get it right."

Those fresh to the Pochettino news, first of all where have you been? But here's a brief summary of what we know so far:

Spurs have appointed Mauricio Pochettino as their new manager on a five-year deal after the Argentine resigned from Southampton having been at the club for only 18 months.

The 42-year-old becomes Tottenham's 10th manager since 2001 and replaces Tim Sherwood who was sacked on 13 May.

"This is a club with tremendous history and prestige and I am honoured to have been given this opportunity to be its head coach," Pochettino said.

Pochettino's assistant Jesus Perez, first team coach Miguel D'Agostino and goalkeeping coach Toni Jimenez have also left Southampton and headed to the capital.

Will he take his interpreter too?
