The Argentine is set to start Sunday’s Premier League clash against leaders Liverpool after David de Gea was injured on international duty with Spain.
Romero has made just seven Premier League appearances for United, but has kept six clean sheets and James believes he is as comfortable as anyone in the Premier League with the ball at his feet.
“I’ve analysed him and there are a few keepers who are highly-rated who just put the ball out there in a general area. But he’s as good as Ederson and Alisson using his left foot and right foot,” James told Goal.
“David de Gea is, of course, the number one, but I looked at Romero when Manchester United bought him and I was amazed at how good the guy is with his feet – then I saw an improvement in De Gea.
“What you tend to find is when you’ve got two keepers or two players training with each other day in, day out, you start picking up positive habits from the other player.”
Ederson and Alisson are considered to have changed the role of the goalkeeper in the Premier League with their ability to start attacks from the back.
“You don’t necessarily have to be as skilful as you would have been 20 years ago when the pitches were bobbly, but it allows a bit more freedom for them,” James added.
“Those two and Jordan Pickford at Everton as well, these guys are very, very good with their feet.
“’Keepers that have that quality, they can kick a decent long ball over 60-70 yards with accuracy as well as make a short pass. They’ve got all the tools in the bag for that.
“But they’ve got to have a decent defence around them. We’ve seen a few times already this season when defenders have messed up and a goal has gone in.
“The defenders you pass to can’t show that they’re under pressure near their own goal and need to be confident and capable enough to deal with it. If you’ve got that then it gives you confidence to pass it to them.”
De Gea has been criticised recently after making a number of mistakes that have cost United points, but James has no doubt the Spaniard will be back to his best soon.
“De Gea has had five amazing seasons at Manchester United. To have six months where you are not at that same level doesn’t mean there’s things fundamentally wrong,” he said.
“It just means to keep that level of performance for so long was incredible in the first place.
“There’s no question that De Gea will return to that kind of form again because he is an exceptional goalkeeper.
“There are lulls in anyone’s performance curve – with Cristiano Ronaldo and Lionel Messi, their lulls are still incredibly high. And that’s what makes them the best in the world.”
