In total, Haaland scored 27 Bundesliga goals and assisted six in 27 Bundesliga starts last seasons, whilst Sancho scored eight and assisted 11 in 24 league starts.
Therefore they had a combined 52 goal contributions in the league in 2020/21, whilst Dortmund scored 75 goals, meaning they were responsible for 69% of the goals scored by the club last term.
What will Sancho add to Manchester United?
In a similar vein to how Cristiano Ronaldo was upset that Mesut Ozil was allowed to leave Real Madrid for Arsenal, Haaland feels the same way in regards to Sancho.
The pair had a telepathic relationship, and that understanding is something that Ole Gunnar Solskjaer will be hoping Sancho picks up with Edinson Cavani and Mason Greenwood.
