Despite never winning a trophy with the so-called "golden generation," Frank Lampard retired from England duty on Tuesday having provided his greatest legacy to football in one game he'd rather forget.

The midfielder prompted the introduction of goal-line technology when he was denied a clear goal in England's humiliating 4-1 loss to Germany at the 2010 World Cup.

Manchester United broke the British transfer-fee record by signing Angel Di Maria from Real Madrid for 59.7 million pounds ($99 million) on Tuesday, extending a summer spending spree that was sparked by its most disappointing season in a generation.

The 26-year-old Di Maria joined on a five-year contract, taking United's spending to about 130 million pounds ($215 million) in the summer transfer window as England's most successful club seeks to revive its fortunes under new manager Louis van Gaal.

While 15-year-old American CiCi Bellis was in the process of stunning a Grand Slam finalist to become the youngest player to win a U.S. Open match since 1996, her father did his best to conceal his emotions courtside.

Like many a teen, CiCi has strict rules for Dad in public — even if his 1,208th-ranked daughter is pulling out a back-and-forth 6-1, 4-6, 6-4 victory Tuesday over 12th-seeded Dominika Cibulkova in the first round at Flushing Meadows.

Pushed deep into a corner, Victoria Azarenka swung from defense to offense with a wicked cross-court backhand winner.

A few moments earlier, she was teetering on the edge of a straight-set loss in the first round of the U.S. Open. Now she pumped both her fists and screamed with all the momentum on her side.

In just his third match in charge of Manchester United, Louis van Gaal oversaw one of the most humiliating losses in the club's illustrious history on Tuesday.

The record 20-time English champions timidly capitulated to MK Dons, losing 4-0 to the third-tier club in the second round of the League Cup.

Everton strengthened its attacking options by signing Samuel Eto'o on a two-year deal on Tuesday after the striker was released by Premier League rival Chelsea.

The 33-year-old Cameroon international, who scored 12 goals in 35 matches in his only season at Chelsea, is available to make his debut against the west London club on Saturday.

Spanish champion Atletico Madrid will have to find a way to win without its inspirational coach for the next month.

The Spanish football federation suspended Atletico coach Diego Simeone for eight matches on Monday after he was sent off for a vehement protest that included tapping an assistant referee on the head during the second leg of the Spanish Super Cup.

Spinning in 70 mph second serves, grabbing at his hamstring during points, Andy Murray gritted his way through head-to-toe cramps to win at the U.S. Open.

Murray outlasted Robin Haase 6-3, 7-6 (6), 1-6, 7-5 in the first round Monday during an afternoon that was hot but not particularly humid. He was mystified that the cramps came on so early — at the start of the third set after only about an hour and a half on court.

Liverpool signed Italy striker Mario Balotelli from AC Milan for 16 million pounds ($26.5 million) on Monday, taking a calculated gamble on a headline-grabbing player known as much for his controversies as his goals.

Nineteen months after ending a two-and-a-half year spell with Manchester City to play for his boyhood club, Balotelli will return to the English Premier League as a replacement for Luis Suarez — another of world football's talented but disruptive stars.

Sitting in the executive seats high up at Etihad Stadium, Mario Balotelli began life at Liverpool by watching his new team ruthlessly dismantled by the club he left 19 months ago.

Manchester City showed just how difficult it will be to dethrone as English champion by beating one of its predicted title rivals 3-1 on Monday, making it two wins from two tough opening games of the Premier League season.
