The International Olympic Committee has sent a clear warning to the organisers of the Rio 2016 Games that "every second counts" after visiting the Brazilian city.
With just over two years to go, the IOC said that a "constant, concerted and integrated effort is required for the successful delivery of the Games and its legacy".
It added: "Although progress is being made, each decision that is postponed and each subsequent delay will have a negative impact on delivery. Total focus and dedication are therefore required."
ITV News' Brazil correspondent Nick Ravenscroft, who was at the news conference, tweeted:
IOC presser re Rio 2016. Time + again say they have been "given assurances" that problems and delays in preparations will be resolved (1/2)
Scepticism from assembled hacks. These sound v much like assurances given re preparations for World Cup. And that's dangerously late. (2/2)
Sir Bradley Wiggins will compete for one more year with Team Sky before retiring from professional road racing next summer.
Speaking of teammate Chris Froome, he said, "I don't mind admitting that Chris is probably a better Grand Tour rider than me. He has age on his side, he has no kids. That's fine. If Chris wants to, he could potentially win five tours now."
Wiggins is setting his sights on a return to the velodrome at Rio 2016, telling the newspaper, "I'm going to continue to the next Olympics and try for a fifth gold on the track, that's the plan".
"It would be nice to finish the career with another Olympic gold," he added.
UK Sport has announced a record £347m funding pot for Olympic and Paralympic sports until Rio 2016, but not everybody is celebrating.Read the full story ›
Let's be honest, I wasn't expecting a great deal of funding from #UKSport, but nothing... that hurts.
Overall we are satisfied with the outcome. While disappointed with the award for swimming, we recognise we need to rebuild confidence that we can deliver medals at Olympic level consistently before we can demand more investment.
We had a disappointing Olympics in swimming and we now need to focus our energies on driving the cultural change needed moving forward and this will be built around a no compromise approach underpinned by performance management and strong effective leadership.
Handball player Chris McDermott has tweeted:
I'm devastated. Absolutely gutted. Gave everything for 7 years now we've been chopped.
@rosiemorris86 Congrats to you guys. Thats with our percentage too so you got an even bigger increase than 53.6%! you'd better do well!
Very happy that @teamgbtaekwondo have secured a 42.7% increase. Well done to all of us. We've had an amazing 4 years..here's to the next 4
The biggest increase of any UK Sport Olympic funding goes to boxing, a 44% increase, to £13.8m, though £9.55m is conditional on sport sorting out some internal issues.
Cycling is up to £30.6m from £26.3m, athletics has a £1.7m increase to £26.8m, rowing up from £27.3m to £32.6m, and gymnastics up from £10.8m to £14.5m.
Investment in Paralympic sport has also risen dramatically, up 43% on London 2012.
Basketball, handball, wrestling and table tennis, have failed to secure investment from UK Sport ahead of the Rio Olympic Games in 2016
UK Sport has announced a record pot of £347m of Olympic and Paralympic sports funding to be distributed in the run-up to the 2016 Rio de Janeiro Games
Cycling, rowing, boxing, athletics and gymnastics have been given increases, but several sports, including swimming, basketball, volleyball and handball, are paying the price for missing medal targets with severe cuts to their income.
Swimming funding has been cut to £21.4m from £25.1m, volleyball (down to £400,000 from £3.5m), plus basketball, handball, wrestling and table tennis, which miss out on funding altogether.
