Al Fahim completed his takeover of the club last week.
The tycoon has given his full backing to manager Paul Hart and chief executive Peter Storrie.
“I asked Paul to accept the role as Pompey’s manager shortly after I was appointed chairman,” Al Fahim told The Times.
“I continue to have great confidence in Paul’s ability to steer the club through the challenges ahead.
“Peter (Storrie) is a capable chief executive and I do not doubt that he has acted with the club’s best interest in mind.
“I decided that it was in the best interest of the club to take over the full 100 per cent, but was kept fully aware of all relevant activity throughout the course of negotiations.
“I was kept fully informed about the transfer dealings and have been consulted on all decisions affecting the club since becoming its owner,” he added.
“We have a clear plan to strengthen the club’s foundations and lay the basis for its development,” he said.
“To achieve this I would anticipate significant investment in the club’s infrastructure, retention of players and the signing of new talent.
“To ensure the growth of the club’s home-grown talent, we will invest in the youth academy, which is vital for any major club’s stable progress.”
