Answers later.

To celebrate, here's a gallery of some quirky Ryan Giggs' moments.

Giggs went on to make a club record 963 appearances for United - and played 64 times for Wales - before hanging up his ell-worn boots in 2014 at the age of 40 to become Louis van Gaal's right-hand man.

It is a momentous day in footballing history.

1991. On as a substitute against Everton. Alas Giggs didn't weave his magic instantly - United lost the match 2-0.

We've been asking if tackling should be banned in school rugby matches. It came after more than 70 doctors and academics called for a ban on tackling in games played in UK and Irish schools.

In an open letter to ministers, they say injuries from this "high-impact collision sport" can have lifelong consequences for children.

But you, the Sportsday readers, are not convinced that banning tackling is the best idea.

8 February, 2000. A great day for fans of then-second-tier Scottish club Inverness Caledonian Thistle, who won 3-1 at Celtic in the third round of the Scottish Cup.

It was also a great day for a sub editor at the Sun, who came up with this fantastic headline.

A Russian team in the Kontinental Hockey League has been fined after its fans used a laser to dazzle the opposition goaltender in a playoff game. 

Mercedes are looking strong in testing. So strong in fact, fans are calling on the powers of Burt Reynolds' moustache to stop them.

Sadly the other teams don't have Burt Reynolds. To find out how they are getting on, head to our live commentary page here.

French prosecutors have widened their investigation into corruption in athletics to include the bidding and voting processes for the hosting of the 2016 and 2020 Olympics.

Lamine Diack, the former president of world governing body the IAAF, isalready being investigated by French authorities.

He was arrested last year on corruption and money laundering charges, over allegations he took payments for deferring sanctions against Russian drugs cheats.

Confirming the investigation was being widened, an official from the prosecutor's office said: "We are looking at these elements, but at this stage it is a question of verification. Nothing has been proved."

Norwich fell into the Premier League relegation zone as Chelsea continued their impressive form under Guus Hiddink with victory at Carrow Road.

Blues full-back Kenedy drilled in from 20 yards after 39 seconds - the fastest goal of the Premier League season.

Diego Costa doubled the lead on the stroke of half-time, running from an offside position to lift the ball home.

Cameron Jerome hit the bar before Nathan Redmond scored as Norwich lost for the eighth time in nine games.

During the Bournemouth-Southampton game, fourth official Kevin Friendcollapsed and hit his head on a dugout.

Friend, who cut his face, was treated in the tunnel before being taken to hospital, where he has stayed overnight.

The incident happened as the first half came to an end at the Vitality Stadium.

The start of the second half was delayed by five minutes as Friend was replaced by Dean Treleaven, a qualified referee who was watching the match.

Bournemouth beat Southampton in the league for the first time since 1958 to move eight points clear of the Premier League relegation zone.

Bournemouth took the lead when Fraser Forster parried Matt Ritchie's free-kick and Steve Cook volleyed in.

Benik Afobe settled the Cherries' nerves when he headed in at the near post from another Ritchie free-kick.

"In previous games we haven't got the goals when we have been dominant," said manager Eddie Howe. "The whole team functioned, and when we play well we are a difficult team to beat."  

So, on that topic, we want to know what you think.

Now then, this is an interesting one.

More than 70 doctors and academics are calling for a ban on tackling in rugby matches played in UK and Irish schools.

In an open letter to ministers, they say injuries from this "high-impact collision sport" can have lifelong consequences for children.

They argue two thirds of injuries in youth rugby and most concussions are down to tackles and urge schools to move to touch and non-contact rugby.

Supporters say rugby builds character and other forms are less challenging.
