JAMES Guy is convinced Tokyo 2020 will be a golden Games for him and Team GB after clinching his second silver medal in the final race of the Rio swimming gala.

The 20-year-old Radcliffe-born swimmer swam the butterfly leg of the men's 4x100m medley as the Team GB quartet of Guy, Chris Walker-Hebborn (backstroke), Adam Peaty (breaststroke) and Duncan Scott (freestyle) smashed the British record in a time of 3mins 29.24secs.

But they were just edged out, finishing 1.29 seconds behind a USA squad that included Michael Phelps up against Guy on the butterfly leg, with the American taking his record-breaking tally of Olympic golds to 23.

Guy said: “We are 21, 20 and 19 – the Americans are quite a bit older than us.

"We are still young, growing lads. We have got so much more to work on."

It was Guy's second silver medal of the Games after guiding Team GB's 4x200m freestyle quartet to second place.

The freestyle specialist, who was fourth in the 100m freestyle and sixth in the 200m, reached the semi-finals of the 100m butterfly and has vowed to concentrate more on his weaker discipline to increase the medley team's chances of gold at the next Olympics.

He added: "Duncan is a young freestyler and I hardly do any butterfly.

“If you compare the size of us (Great Britain) to the US, Texas is three times bigger than Great Britain, and there are 50 states.

"The variety they have is special, but for us we are a small country and are up and coming.

“We are up with them, we came second and it was great race. There is so much to work on and Tokyo is going to be the one I think.”

While Guy believes there is more to come, he still contributed to Team GB's most successful Olympic Games in the swimming pool for well over a century.

Silver in the medley took the British squad's total in the pool in Rio to six, their best haul since London 1908.

It also contributed to Team GB’s most successful day at Rio 2016 yet with eight medals – three gold, four silver and one bronze – to push the overall total for the Games to 30.

While Guy was busy making history for Team GB, he was more interested in the part he played in Phelps' historic 23rd gold medal.

The big American's tally is a long way past his nearest rival, Soviet Union gymnast Larisa Latynina, who won nine between 1956-64.

“To be beside the greatest of all time in Michael Phelps is pretty special," he said.

"I have watched him since I was a young boy and to race him and go head-to-head is pretty special and something I will never forget.

“To say that I was head-to-head with him in his last race is special but I don’t think he’ll retire.

"I think he’ll go on to Tokyo 2020. I think he wants 25 golds – he has got 23 and I think he wants two more."
