Gill spoke following United's flotation on the New York Stock Exchange this month, an attempt by the club to obtain additional funds and reduce the level of debt at Old Trafford.

He stressed the new financial structure put in place by the club means they will continue to be able to spend money on improving the squad.

"We fully understand and the owners fully understand that what happens on the pitch is crucial to us and we will make sure there are sufficient funds to invest in the team going forward," Gill told reporters.

Referring to the club's owners, the Glazer family, the chief executive said: "The level of debt that we've had at the club since they've taken over hasn't impacted on what we've done as a team."

The 55-year-old pointed to the club's recent success in the English Premier League and the Champions League, as well as the agreement of a seven-year shirt sponsorship deal with Chevrolet, to underline his point that the club can continue to progress regardless of the debt.

"We've won four Premier League (titles), we've been to the Champions League final three times (under the Glazers), we've had ongoing success on the pitch," he said.

"We're comfortable with the leverage we've had and we believe that given the growth opportunity we've got ahead of us - for example we've signed Chevrolet to a seven-year shirt sponsorship commencing in 2014, which is over twice what our current shirt sponsors make - we've got a lot of interesting and good opportunities to improve our cash flow going forward."
