Formations We Can Expect
Solskjaer usually plays one of the following three formations. A 4-3-3, 4-2-3-1 or a 4-5-1. He likes his sides building from the back and hence needs ball playing defenders. Fullbacks go high up and complement the wingers. A fluid frontline is something we can expect.
The 'babyface assassin' could get the best out of Pogba and bring back exciting and expansive back to the red half of Manchester. A 4-2-3-1 setup with de Gea in goal. Shaw and Dalot as fullbacks with Lindelof and Smalling or Bailly at centre back.
Pogba could partner Herrera in the middle of the park with Mata as the creative player. Rashford down the left, Martial or Lingard down the right with Lukaku as the main striker.
Lukaku would benefit a lot from this system as the likes of Pogba, Mata and Lingard could put-in accurate balls for him to head in and play to his strengths. The presence of a creative no10 would ensure that he doesn't get isolated as he did in Mourinho's system.
Herrera and Pogba would be the perfect combination as the former would sit back and provide defensive cover and win back balls allowing Pogba to carry the ball forward and join the attack. Rashford, Martial and Lingard would all have the freedom to either cut in or stay wide and cross the ball in.
Defensively his sides usually press high up the field as soon as they lose the ball but fall back into a compact 4-4-1-1 formation, ready to break on the counter as soon as they win the ball back.
