Van de Beek has made 10 Premier League appearances for United in total and scored his only goal in the 3-1 win over Crystal Palace in September.
The 23-year-old has yet to assist a goal and has created just two big chances for his team-mates across those 10 matches.
His average of 50.2 passes per 90 minutes ranks below fellow midfielder Bruno Fernandes (60.17), Paul Pogba (62.02), Fred (62.85) and Nemanja Matic (76.08) but above Scott McTominay (48.37).
Van de Beek ranks higher for dribbles completed (1.43), however, with Pogba (1.75) the only midfielder above him in that metric.
Solskjaer continued: He knows he is important for us and knows he is going to play many games.
He will definitely be involved in this game against Liverpool and he might be the deciding factor in the game.
He trusts his own quality. He is a quietly confident guy who deep down knows he is good enough and is just waiting for his opportunity.
Having been used in a variety of roles in United s midfield, Van de Beek – utilised as a box-to-box threat during his Ajax days – scored 28 goals in total in the Eredivisie.
Arguably his most impressive form for Ajax came in the 2018-19 Champions League campaign, with his four goals helping the Dutch giants to the semi-finals.
