ALLEN PARK, Mich. — By Eli Manning standards, this was quite a put-down.

Manning came off the field after Wednesday’s joint practice with the Lions and was still perspiring when he was informed that Jalen Ramsey, the Jaguars’ top cornerback, ripped him. Ramsey, in a full-scale assault in an interview with GQ, offered his critique of several of the NFL’s veteran quarterbacks, including Ben Roethlisberger, Matt Ryan, Andrew Luck and Joe Flacco, plus calling Bills rookie Josh Allen “trash.’’

This was Ramsey’s take on Manning: “It’s not really Eli. I think it’s Odell Beckham Jr. I won’t say Eli’s good. I’ll say Odell’s good. And their connection is good.’’

Manning looked surprised by this analysis. Asked for a comment, he said, “No.’’ And then, after a pause, he sort of winked and said softly, “Who?’’ Then Manning smiled.

Clearly, Manning knows who Ramsey is. Clearly, he is not sweating anything Jalen Ramsey says.

Just as clearly, Manning never, ever, pours kerosene on a fire, as that is not his way. Just as clearly, the ultra-talented Ramsey likes to shake things up. He currently is serving a one-week suspension imposed by the Jaguars after Ramsey served up an obscene rant against the local Jacksonville media.

“I feel everybody has their own personality traits,’’ Patrick Omameh, the Giants’ new starting right guard, told The Post. ”For whatever reason, the news likes to focus on Jalen and what he has to say.’’

Omameh was Ramsey’s teammate in Jacksonville the past two seasons and, though Omameh had no interest in dissecting Ramsey’s harsh assessment of Manning — “I mean, people talk, I don’t pay no mind,’’ he said — there was a quick defense of the 37-year old quarterback about whom Omameh is learning.

“The man is a consummate professional and just a natural leader,’’ Omameh said. “You are around him, you just get the sense this guy, he’s been here before, and he has. He carries that with him. He’s a guy that knows how to get stuff done, and as an offense you can respond to that.’’

There is no doubt Manning is enhanced by having Beckham as a target. Although the two have been prolific together, Beckham missing so much time last season with a fractured left ankle has impeded the on-field relationship from growing even more effective. Watching them carve up the Lions for a second consecutive day gives the appearance that Manning and Beckham are completely in sync, but the fact that they often spend time after practice working together is an indication they are not.

“We’re getting there,’’ Manning said. “We still got some work to do. I think he’s done a good job the last few weeks kinda getting his feel back and his rhythm, how to work guys in man, give ’em an extra moves, trusting his body. He’s getting back into a zone and we’re getting comfortable on the field again.’’

When they remain on the field after their teammates are already out of the hot sun, Manning said, they are not going over basic routes and concepts. Rather, they are fine-tuning the minute details that can turn an incomplete pass into a connection or a small gain into a big one.

“Instead of just saying, ‘Here’s a route, run it,’ you say ‘Here’s a route, this is the coverage, this is the technique,’ ’’ Manning said. “Make sure he’s seeing things the same way so we’re expecting the same things. Make sure we’re good with the depths of things and the angles coming out of the breaks.’’

This is the work Manning prefers and craves. What a cornerback from another team says about him — even a talented one such as Ramsey — does not hold much interest to him.

“Eli got here because he’s a hard worker, he’s a great quarterback,’’ said cornerback Eli Apple, Manning’s teammate. “He’s somebody that’s very accurate, he watches a lot of film, puts a lot of time in. He definitely has the talent, even now, he’s still very cerebral in the game. He’s still a great quarterback.’’

Reminded of Ramsey’s rip-job and that cornerbacks often like to talk, Apple said, “Exactly. Most of them.’’

The Giants play the Jaguars in the Sept. 9 regular-season opener at MetLife Stadium. Perhaps Manning before the game will go over and introduce himself to Ramsey.

“I hadn’t heard anything about it,’’ Manning said. “So hey, I got work to do. I’m going to be excited about Week 1 no matter what.’’
