David Eaglesham: It would have to be the Wimbledon men's trophy. It is just so iconic. Close second would be the European Cup, old big ears.

One young lady is up and hollering right down the barrel of the television camera such is her excitement at a deft little Jamie Murray half-volley for 0-15.
Andy Murray dinks away a little angle to bring up 40-30, but David Goffin catches a smash cleanly to close out the game and put a dampener on the British gurning.
For now at least...

Oh my!
Great Britain slither off the hook at 0-30 down as David Goffin's heavy handed volley slips wide to end a rally that the hosts had the upper hand in.
That could easily be 0-40 and three break points Belgium.
As it is, they have one break point to deal with as Jamie Murray bumps long with a backhand volley at 30-30.
Image source, Getty ImagesSteve Darcis comes under the microscope at 15-30. Pressure on the Belgian. A break here and the match is fast getting away from them.
He thumps a forehand right towards the sternum of Jamie Murray, who cannot rearrange his limbs quickly enough to return.
Home and hosed for the hosts.

"It's been an ear-splitting 45 minutes, interspersed with a little of the hissing between Andy Murray serves that featured in Friday's singles, but the world number two took a grip on proceedings and celebrated as never before bearing in mind it was just the first set.
"It's the drums and brass band in the British section making the most noise just now, and the giant surreal cardboard faces of Darcis and Goffin are nowhere to be seen."

Andy Murray comes to the rescue in the next point. Not with an arcing ace, but a glorious stop-volley that dies out of reach of Steve Darcis.
But Great Britain are up against break point as Darcis shows similarly fine touch.
Saved by a Murray serve that kicked like a mule around Darcis' lugholes!
