Here’s why he’s wrong.
One of Kanchelskis’ main points of doubt over van Gaal was that he didn’t understand the system and brand of football the Dutchman was trying to use at Old Trafford.
In LvG’s defence, it’s been difficult for him to select a side consistently this season because of the number of injuries the team has had to key players.
If a manager can’t select the same sort of team on a weekly basis, it’s always going to be difficult for that side to secure consistent results and play impressively.
Van Gaal has had to use different systems and introduce new players into his team to cope with the personnel available to him.
His hands are also tied to a certain extent with regards to the January transfer market.
The club spent big last summer to try and raise quality levels at Old Trafford in terms of playing staff, but the huge spending always meant it was going to be difficult to spend again (because of Financial Fair Play), in the middle of the season to mount a title push.
However, the signings from last summer will be well bedded in ahead of next season and the boss can go again in terms of making squad changes this summer.
Van Gaal has also gone through this before and he has developed young sides in previous jobs, while getting the best out of his more established stars.
Kanchelskis’ claim is based on a few difficult months where van Gaal has been coaching his side under less than ideal circumstances.
He’s also been coaching them with the main aim of getting back into the Champions League, not winning the Premier League title.
If his job was on the line and the main aim was winning the league this season, he may have coached the side differently and it seems a bit premature to judge a potential ten-year spell based on five months.
