ENGLAND captain Eoin Morgan and head coach Trevor Bayliss have backed James Vince to come good against Australia at Lord’s today.

The Hampshire captain is set to play in arguably the biggest match of his career as England look to bounce back from their shock defeat against Sri Lanka.

Vince was only expected to play two matches while Jason Roy recovered from his hamstring injury.

But despite being out for 26 and 14 against Afghanistan and Sri Lanka, Vince is set to play the Aussies at the home of cricket in a match that has come too early for Roy.

The Surrey batsman returned to the nets for the first time since tearing his hamstring yesterday, but Bayliss has vowed not to include the him until he is fully fit, meaning another chance for Vince remains the best bet.

After confirming Roy would not be facing Australia, Morgan gave Vince a strong vote of confidence at yesterday’s press conference.

“Of course Jason Roy’s a big loss, he’s an outstanding performer for us. But I’m confident we have the batting covered,” he said. “James Vince is an extremely talented, gifted player. You can see that just watching him.

“We’ve every faith in him to go on and get a score at some stage.”

Bayliss concurred: “He (Vince) looks a million dollars then he finds a way to get out.

“Hopefully he’s one of those guys who can put one together and it tips him over the edge and he gets a string of big scores.

“He’s certainly a good player, but he’ll be looking to play a longer dig.”

There is a possibility that Vince will be needed to play in another huge game against India at Edgbaston next Sunday.

“Jason went for a scan this morning, he won’t be fit for [Australia] and we’ll monitor his progress in the week,” added Morgan.

“To put one game on it (for Roy’s return) I don’t think is sensible, let’s just see how it goes.

Defeats to Sri Lanka and Pakistan leave England needing perhaps two wins from their remaining three round-robin matches against Australia, India and New Zealand to reach the semi-finals.

But Morgan rejected the idea Tuesday’s clash at Lord’s is already a do-or-die situation for England.

“It’s not must-win yet,” said Morgan.

“We don’t need to win every game to get to the semi-final.”

Australia will return to the top of the World Cup standings and all but secure a passage into the semi-finals if they can deepen England’s misery when the sides meet at Lord’s.

The defending champions have won 13 of their last 14 one-day internationals and, ominously for Eoin Morgan’s side, seem to be peaking at the right time.

Meanwhile, Jonny Bairstow, Vince’s opening partner, expects Steve Smith and David Warner to face plenty of barracking from England fans as cricket’s oldest rivalry resumes.

Reacting to pleas from Australia coach Justin Langer for spectators not to boo Warner and Smith, Bairstow told the Daily Telegraph: “I am not sure that makes any difference.

“The fans will react however they want, particularly in the Ashes. It is a bit pointless pleading with them not to boo Smith or Warner.

“There is a fine line as well. There was a time not that long ago when the then-Australia coach, Darren Lehmann, was telling the Australian crowd to ‘send Stuart Broad home crying’. I’m sure it wasn’t meant maliciously, but for Australians then to say ‘do not boo these guys’ is interesting. It has to work both ways.”

“I’m not saying it is right or wrong. But to have the mentality ‘we can do it to you, but you cannot do it to us’ is a bit strange.”
