Interesting about Luke Shaw there: When Paul (instead of Marcus) played on the left, Luke had to go (on the wide runs) more often. And: He’s a very talented young boy that I sill want to push on.
Both explains how there are tactical reasons (the exploitations of Rashford’s strengths) why Shaw isn’t the most active full back in the last third, and confirms that Solskjær sees Shaw as a player that both needs to be pushed and cared for in order to build his confidence to a level that matches his physical and technical talent.
We all remember how Mourinho did the pushing part without the caring for part, with some bad results. I still see Shaw and Martial in a similar way there, and how Solskjær will develop their top talent where Mou would squeeze them and sell them if his methods didn’t suit them, replacing them with 28-30 year old soldiers.
