​It might sounds silly but Mauricio Pochettino needs to go full Mauricio Pochettino to kick-start his Manchester United reign. He has to go hard early. Pochettino is intense, demands incredible levels of fitness and dedication from his players and staff, and puts egos aside to make surprising and ruthless calls.He needs to double down on all of that as soon as he arrives in Manchester. Fast start key as fixtures are there for the takingWhen he’s come in to any club, the first thing Pochettino focuses on is sorting out the defense. He did that midseason at Southampton and that propelled them to a very strong second half of the campaign in 2012-13 and then an eighth-place finish the next season. At Spurs it was slow going to start with but eventually their defensive unit was sorted out and it was the bedrock for their incredible five years under Pochettino where they finished fifth, third, second, third and fourth in the league.

High-pressing is the cornerstone of his tactics and these young talents are waiting for the chance to develop under the right manager. Pochettino is that manager and we’ve already seen flashes of brilliance from Lacey, Amass and Heaven in particular. Look at Harry Kane, Dele Alli, Luke Shaw, Adam Lallana and Cole Palmer, to name a few, who dazzled as youngsters under Pochettino and became stars. There are also plenty of other top young talents in United’s academy who will be pushed through in the coming months. That’s how he rolls. Pochettino isn’t scared to give chances to youngsters and given the situation they’re in, United’s seniors players can’t argue with having to wait for opportunities to get back into the team. Make ruthless decisions to inspire and gain respectPochettino is all about the strength of the group being more important than individuals. Big egos and people cutting corners just doesn’t work with him. He has to double down on that in his early days at United. Even though it’
