COMMENT: It's not intentional. He doesn't do it on purpose. But when Marcus Rashford is poor, he really is poor...

For these pundits, this shouldn't be personal. It shouldn't be any type of hatchet job. They've been there themselves. No man has a career on a constant upward trajectory. There'll always be peaks and valleys. And at the moment, Marcus Rashford is enduring one of those valleys.

This is no column for excuses. We're not running interference for Manchester United's No10. Indeed, when the ball doesn't stick. When it's bouncing off your ankles. The very least you can do is work like no other when out of possession. Unfortunately at St James' Park on Saturday, Rashford failed to do just that - and was rightly hooked by his manager.

But this is no downing of tools by Rashford. No protest against Erik ten Hag. We've seen all this before. As we say, Rashford doesn't do this on purpose. But when his form hits a slump it really hits a slump.

The touch isn't there. Nor are the reactions... the speed of thought. If you really study Rashford's game, you can see he's a yard slower than everyother player on the pitch - both physically and mentally. But this is Rashford. He gets himself into these spirals and has always battled to find a way out.

Which is why Ten Hag continues to play him. At the moment, for this column, Rashford is a liability. He's effectively Paul Pogba at the Frenchman's worst. Being caught in possession. Spraying loose passes infield. Allowing his marker to run off him. His presence in recent games has hurt United. That run of form in the Premier League - before Newcastle - was achieved despite Rashford's contribution, not because of it.

But you can understand Ten Hag's persistence. Rashford isn't going to rediscover his best sitting behind his manager in the dugout. He needs to be on the pitch. Be involved. Keep showing. Keep persevering. Even when nothing is coming off for him - as is happening at the moment.

And to be fair, this is exactly what Ten Hag articulated after that 1-0 setback on Tyneside: “I will talk to him and not the media.

“I know this issue's coming up and Marcus is investing a lot. We support him and he will return to his form.

“I repeat myself: he works hard and he's investing a lot, he will get back, he will recover and he gets all our support."

If Rashford was acting up. If he was being a strop. We'd know about it. Ten Hag never shy in letting fans know if a player has upset him. And it's clear that's not the case for Rashford.

The wobbler at his substitution is now being scrutinised. And you can understand it. But we'd argue it would've been far more worrisome if Rashford had simply accepted his number being called, shrugged his shoulders and passively jogged off the pitch without a whimper. But there's still spirit there. Still anger. Passion. It's not working for him, but it's not for want of trying.

The question is: how long does Ten Hag stick with his attacker? On Saturday he had Antony and young Facundo Pellistri on the bench. On current evidence, neither player would be a step down from what Rashford is currently producing. Again, it shows how much Ten Hag believes in Rashford's talent and how much he's willing to sacrifice to help him snap this slump. If the manager really was all about playing favourites, it'd be Rashford out and his former Ajax man Antony in. Indeed the Brazilian, once introduced, almost earned United an unlikely point if not for Harry Maguire's offside call.

But Ten Hag, as he suggested post-match, will stick with Rashford. And he won't be reacting to what the ex-players demand. Paul Scholes and Jermaine Jenas had their say on Rashford in the aftermath. "Lazy". "Criminal". They took their shots. But we've all heard it all before. We've seen it all before. This slump is nothing new. What could be new is if one of these pundits would actually take the public through how they snapped such troughs. Even Scholes had his down moments in a United shirt. Instead of doing the routine thing of reacting and attacking, it would actually be good to hear - and in detail - from one of these greats about how they would overcome such moments in their careers. It won't mean clicks or pats on the back from the producer, but it would be instructive for any young hopeful watching.

And it could even help Rashford. After all, none of this is intentional. It's just another one of those typical deep form slumps from United's No10.
