I believe the signing of Eriksen will assist Ronaldo to score more goals if he decide to stay atleast for now that Chelsea had backed out from the purported bid, Man Utd lacked creative midfielders that can create the finals passes, the present crop of players playing that role had not live up to expectations, Bruno Fernandez had performed woefully in that role, honestly if Erik Ten Hag can rebuild the team with players like Eriksen who has the capacity to create goal scoring chances because of his passing ability will help the team precisely Ronaldo to score many goals.
Eriksen will be a good alternative for Bruno when Bruno is suspended by card quota, injury and loses his best form. Eriksen is a good replacement for Pogba too. With Eriksen, Manchester United has another attacking midfielder but still be able to give them safety for their goalkeeper.
Eriksen has better teammateship and is ready to sacrifice his own benefit personally. United got good result from friendly match but theri squad with old and new players will be tested more seriously with last core tactics for United, until it changes.
