Michael Brown has warned Newcastle United it will take a “long time” to transform the club into an expansive, attack-minded side.

The former Leeds United and Spurs midfielder, speaking exclusively to Football Insider correspondent Dylan Childs, identified Aston Villa and West Ham as examples of how investment brings no guarantees.

The Premier League is in the final stages of ratifying a £300million takeover of the Magpies by the PCP Partners, a Saudi-backed consortium, from Mike Ashley.

As revealed by Football Insider, the prospective new owners plan to initially invest £200million into the club’s recruitment and infrastructure in a transformation of ambition.

However, Brown suggested the defensive set up that has been implemented at St. James Park in recent years will make it difficult for rapid change.

“The stadium and fan base are there,” he told Football Insider.

“But on the field, you have seen with Rafa Benitez and Steve Bruce, they have had to play a system where they are hard to beat. It is not always entertaining for the supporters but it keeps them in the league.

“There is going to have to be ridiculous backing to change that quickly. It takes a long time to make that progression from a defensive system to a flowing, open one.

“We have seen teams come unstuck trying to do just that – Aston Villa and West Ham have spent huge amounts and they are both fighting relegation. It is a fine balance.”

Aston Villa have spent £143million on transfer fees since returning to the Premier League just under a year ago.

Villa, 19th, and West Ham, 17th, are deep in a relegation battle despite large investment into their first-team squads.
