Ali Al Faraj is ready to plough big money into Portsmouth after completing his buyout this week.
Al-Faraj's lawyer Mark Jacob, revealed: "There is going to be substantial investment.
"We were ready to invest and push things forward six weeks ago so that was a missed opportunity. However, there will be funds available in January to ensure we are not at the wrong end of the table come the end of the season.
"Both (the training ground and new stadium) are part of our plans but the most important thing after this difficult period for everyone at the club is to achieve some stability.
"We will be working closely with the executive board and senior management on all aspects of the club's infrastructure and our goal is to improve every area of the business both on and off the pitch."
