Delve into the history books to see what happened "on this week" in sport.

1994: Senna killed in a car crash - May 1

Brazil was plunged into a state of mourning on this week back in 1994 when Ayrton Senna crashed his Williams car into a wall while travelling at 192 mph during the San Marino Grand Prix (pictured). It was a double tragedy for Formula One as the previous day Austrian driver Roland Ratzenberger was killed at almost the same spot. Senna had won 41 grands prix and three world championships at the time of his death and had already cemented his place as one of the sport's all-time greats.

Senna was only 34 when the tragedy occurred and half a million people attended his state funeral in Sao Paolo. In 1997, Williams-Renault team principal Frank Williams, team designer Adrian Newey and technical chief Patrick Head stood trial for manslaughter under Italian law, having been accused of being responsible for faulty steering in Senna's car. They were later acquitted.

1993: Monica Seles is stabbed - April 30

Gunter Parche did Steffi Graf a horrible favour that she never asked for on this week in 1993 when he stabbed the then world number one Monica Seles in the back. Seles had emerged as the world's top player over the previous couple of seasons, ending a long period of domination by Graf.

However, Parche, an obsessed fan of the German, ran onto the court in Hamburg as Seles took on Maggie Maleeva and stabbed her in front of six thousand fans. Seles was initially expected to be out for four weeks, but it was over two years before she would take to the court again. Even then, she truly was never the same player again.

Graf regained top spot, while Parche received a two-year suspended sentence and mandatory psychological treatment for "causing grievous bodily harm". However, he escaped an attempted murder charge, much to the distress of the Seles family.

1956: Rocky Marciano retires unbeaten - April 27

On this week back in 1956 Rocky Marciano announced his retirement from boxing to become the first heavyweight champion to leave the sport undefeated. His remarkable record remains in tact to this day. The 'Brockton Blockbuster' finished his career with 49 wins, 43 KOs and no defeats.

In the six fights that went to a decision, only one was split, against Roland La Starza, and Marciano later went on to stop La Starza in a rematch three years later. Marciano was knocked down only twice in his professional career. The first time was in his first championship bout against Jersey Joe Walcott, and the second against Archie Moore in his final fight. On both occasions, Marciano rose to knock his opponent out. In other words, he was pretty good at boxing.

1923: The White Horse FA Cup final - April 28

Ahh, don't you just love those old FA Cup clips? And is there any more memorable image than the 'White Horse' dispersing the Wembley crowd in 1923? Good old Billie (his name is a great quiz question by the way) is up there with the World Cup-finding dog Pickles as one the most famous football related animals of all time. I can't actually think of any more but that's not the point!

The first match staged at the magnificent 127,000 capacity stadium was the 1923 FA Cup final between Bolton and West Ham and the authorities thought the ground was big enough to avoid issuing tickets in advance. As we now know that was a big mistake, as a crowd of somewhere between 240,000-300,000 packed the stadium. Billie and his police chums managed to restore some level of order and Bolton won the match 2-0.

(Un)Interesting fact about Billie: he was actually grey but it was the old newsreel footage that made him appear white.

1908: London Olympics gets underway - April 27

The organisers of 2012 should take note of how to develop a cost-effective Games from their counterparts that arranged the London 1908 Olympics. Then the city stood in just two years before the event was due to take place when Rome had to pull out due to the eruption of Mount Vesuvius, which saw funds redirected to Naples.

London built the 68,000 capacity White City stadium in just 10 months for a mere £60,000. The venue also hosted the Franco-British Exhibition, which was actually considered a bigger deal at the time.

The opening ceremony was held on this week 100 years ago and was not without controversy due to a number of 'flag' incidents. Finland marched without a flag as they were expected to compete under the Russian flag; Sweden refused to take part in the ceremony because their flag was not displayed above the stadium; and for a similar reason, the USA didn't tip their flag to the royal box. The Games ran until October and Britain topped the medal list with a whopping 146 (56 of which were gold). Beat that in Beijing boys and girls!
