Eric Molina admits he could not cope with Anthony Joshua's speed and power on Saturday night

Eric Molina admitted that Anthony Joshua's speed and power was 'overwhelming' as he reflected on his stoppage defeat by the IBF heavyweight champion.

The American challenger climbed up from a heavy knockdown in the third round, but was rescued by the referee as Joshua followed up with another flurry of punches at the Manchester Arena on Saturday night.

Molina felt his preparations were not ideal for a world title fight against the unbeaten 27-year-old, although he gave credit to a 'great champion.'

I went for it, but that's boxing and it's never easy to win on the road. Joshua is a great champion.

"We took on a strong champion as a late replacement," Molina exclusively told Sky Sports. "Joshua's speed and power were overwhelming. I definitely tested the limits and failed.

"It seemed like I couldn't snap out of jet lag the entire camp. Thirty nine days to prepare, with five of those spent in the air.

"I went for it, but that's boxing and it's never easy to win on the road. Joshua is a great champion."

The 34-year-old found it hard to settle into the fight and accepted that Joshua did not allow him to execute his pre-fight tactics.

"Our plan was to weather the early three or four rounds and then open up," said Molina. "Not every plan works every time, obviously.

"Nonetheless, I am grateful for the opportunity to fight for the heavyweight crown."
