Manchester United was convincing with their performances in the game against Leicester City no doubt and in as much as I totally agree with you opinions that it was because of the tactical approach Ruud Van Nisterooy adopted which was clearly different from what we were seeing when Erik ten Hag was still in charge, I suggest we wait for when the team under the interim manager will face a stronger team like Chelsea who they face this weekend in the English Premier League Chelsea before we can ascertain the effectiveness of Van Nisterooy's effectiveness.
A 5:2 win against Leicester City is a good result but winning with such amount of goal margin against Chelsea will be a great result.
If you keep the match of these two separate and emphasize the performance of Manchester United, then it is not such a special record. But in this match, Manchester United has scored 5 goals and won by 3 goals. The match between Chelsea and Manchester United will be tough but I see the victory of Chelsea because Manchester United played this match well but Chelsea is a strong and standing top team. That why I don't think Manchester United can win but they can draw the match.Chelsea are a strong team and have the power to score so many goals themselves. In which Manchester will find it difficult to score more goals. But their players manage to score first by applying pressure. So these matches as much goal as they can otherwise Chelsea will win the match by scoring more goals.
In this match, Manchester United has shown strength and speed along with good performance but the real performance will be known in the match against Chelsea.
