Floodlights were installed at Sophia Gardens for this season

The Welsh county recently announced �6m plans to develop Sophia Gardens to meet Test match standards, but the team face relegation from both leagues this term.

"Expenditure on a player is a cost - it is never recovered," Russell told BBC Wales Sport.

"What we're doing with the ground is an investment and over a period of time we will earn more money as a result."

Croft targets three one-day wins

Glamorgan were promoted to the County Championship Division One last season as Division Two champions.

But Robert Croft's side have lost 11 of their 12 matches this season and need a dramatic run of form to avoid going straight back down.

Croft also lifted the Totesport League One title last season, but the Dragons currently occupy the third relegation place with six games to go.

Our concentration now is achieving success in all areas rather than taking out the surgeon's knife Glamorgan chairman Paul Russell

Glamorgan's decision not to sign a second oversees player to join Australian batsman Matthew Elliott has been widely criticised, but Russell said: "We won games last year without an oversees player in our team.

"We conducted the whole of our preliminary round in the Twenty20 Cup without an oversees player.

"And let me emphasise, the money that's being spent on the stadium at Sophia Gardens is an investment and will result in the club being far better off financially.

"The banks and financial institutions will happily lend you money to develop the ground to stage international cricket etc, they won't lend you money to buy another player."

Russell added the management team will consider a change of coach and captain at the end of the season.

But he stressed that consultation process happens each year.

"At the end of every season every part of our performance is reviewed against the objectives we set.

"Our concentration now is achieving success in all areas rather than taking out the surgeon's knife as it were."
