LONDON, England (CNN) -- Chelsea want to be a dominant force in world football. Chelsea also want to become a successful global brand. If that's the case, Chelsea should take a long look in the mirror and examine the irrational decisions which have left them in disarray:
Wrong decisions: Pedro Pinto says Chelsea should never have sacked Jose Mourinho.
1. Sacking Jose Mourinho
Releasing the most successful manager in club history midway through his fourth season was a significant mistake.
It's true some players allegedly grew tired of the Portuguese manager's ego and his need to control everything at the club, but if he would have stayed, Chelsea would not have ended last season empty handed and they certainly wouldn't be languishing in fourth place in the league table in the present campaign.
Roman Abramovich and the Chelsea board should have stuck with Mourinho, even when there was a temporary decline in results and performances.
2. Hiring Avram Grant
The Israeli manager finished his tenure at Chelsea with a good record, but he never had the full backing of the players and everyone knew he wasn't going to stick around for long.
To sack Mourinho when they did, Chelsea should have found a long-term replacement. It would have been smarter to wait a bit longer and draft in an experienced coach, such as Marcello Lippi or even Guus Hiddink.
3. Keeping disgruntled players
Didier Drogba, Wayne Bridge, Florent Malouda and Salomon Kalou should all have been shipped out in the summer. The Ivory Coast forward repeatedly stated his desire to leave the club and was allowed to stay.
He has been a destabilizing influence in the dressing room, and keeping fringe players who weren't good enough to feature consistently in the starting XI wasn't a good move either. Their sales could have funded the signing of another quality winger and an experienced marksman.
4. Sacking Luiz Felipe Scolari
Seven months was not enough time for the experienced Brazilian manager to make his mark on the club. Injuries to Michael Essien, Joe Cole, Ricardo Carvalho and Drogba have affected Chelsea's season and I believe it's unfair to put the blame on Big Phil.
It's true he should have shown more tactical awareness by employing an alternate 4-4-2 formation, especially when playing at home, but he deserved more time. His record speaks for itself and I believe he would have been able to turn the Blues' season around.
5. The Credit Crunch
It has been estimated that Roman Abramovich may have lost over $3 billion of his fortune since the beginning of the economic crisis. The financial hit has certainly affected Chelsea's dealings in the transfer market.
For the first time since the Russian billionaire took over, the Blues didn't spend a cent in the winter transfer window, when they clearly needed another striker and even another winger. His lack of spending definitely contributed to Scolari's demise.
