South Africa won the toss and sent an under-pressure Australia in to bat in their triangular-series which also features Zimbabwe.

Australia have lost their last two games in the series, including a surprising defeat against Zimbabwe on Sunday, to slip from first to number four in the ODI rankings. The Aussies also lost captain Michael Clarke for the rest of the series to a hamstring injury.

Japan's Kei Nishikori outlasted fifth-seeded Canadian Milos Raonic 4-6 7-6 (7-4) 6-7 (6-8) 7-5 6-4 to move into the US Open quarter-finals at 2:26am New York time, in the joint latest finish ever at the tournament.

It spanned four hours and 19 minutes, equalling two other marathon contests played at Flushing Meadows, between Philipp Kohlscheiber and John Isner in 2012 and Mats Wilander and Mikael Pernfors in 1993.

In his first interview as a Manchester United player, Radamel Falcao told MUTV it was a dream come true for him to play in the Premier League and predicted a "great" season for the new-look Red Devils.

"It was a very long day," he says after securing a season-long loan move. "It was hard, difficult. We were waiting until the last minute but I didn't lose my faith. Now I want to say thank you to God for this. I'm very happy.

"For me, it was a dream to play in the Premier League. I always wanted to be here because this league is very good, it has very good teams and Manchester United is the best team in England. Everything is perfect for me."

Former Manchester United assistant manager Mike Phelan with some forthright opinions on 5 live Breakfast following the sale of Danny Welbeck to Arsenal. "Interesting how things have changed at Manchester United now. A good young kid coming through - part of the academy system - and they've decided now that might not be the way to go so they've moved him on," he says.

"Obviously there is more and more money now in the game, looking further and further afield for players but probably they have lost the way of Manchester United a little bit in the fact that now rather than produce it may be the case where they're buying in."

Also today, European captain Paul McGinley names his three wildcards for the Ryder Cup at Gleneagles, we'll be hearing from England boss Roy Hodgson ahead of tomorrow night's friendly with Norway, there is news from the US Open and England need to beat India at Edgbaston to keep the one-day series alive.

BBC Sport's chief football writer Phil McNulty casts his eye over the transfer window dealings and how they may affect the Premier League season.

OK, you're busy people. You might prefer a simple chronological list of the transfers. You can find that here.

The deals were still being completed in the early hours of this morning and you can relive the drama as it happened in our comprehensive transfer deadline day live text.

United have, of course, made the headlines with their high-profile deals, but Arsenal have signed Danny Welbeck for £16m, Hull have made some shrewd signings, and Harry Redknapp has recruited two of his former players for QPR. Who do you think has done the best business in the transfer window? Please let us know at #bbcsportsday.

Hello and welcome to Sportsday. So, £835m. No, not Radamel Falcao's weekly wage at Manchester United but the gross total spend in the summer transfer window. The transfer intensity may be over until January but there is plenty to digest.
