Forwards and physicality in a back 3 system

Watching and hearing all the analysis after Ipswich has had me thinking a lot about the back 3 and our forward options.

With a back 3 we are trading 1 forward for the extra defender, increasing the physical burden on the front 3 to deal with 4 defenders in buildup. Assuming Bruno will be one of those 3 forwards, that burden seems even greater on the other two attackers.

Against Ipswich we saw this in display somewhat with Rashford (who is not particularly good with physical duels) struggling to get touches in those tight spaces, and Garnacho favoring open spaces in wide areas for his runs. As you mentioned in the pod the buildup got much easier once Hojlund came on to run the channels while holding off defenders to progress the ball.

Am I correct in understanding that this system makes that a bigger problem with our limited options in physical forwards? Considering this especially increases the burden of physical duels for the striker, would this limit the output of the striker getting behind goalscoring opportunities?

How do you think Amorim will go about tackling this issue with the players on hand?
