Sheffield Wednesday's first-team coach Lee Bullen has no doubts current manager Stuart Gray is the right man to take the club forward under new owner Hafiz Mammadov.

Azerbaijani businessman Mammadov, founder and chairman of the Baghlan Group, which specialises in oil, gas, construction and transportation, completed his reported £40million takeover on Tuesday.

The deal has yet to be ratified by the Football League, but Mammadov, who also owns Azerbaijan side FC Baku and French Ligue 1 club Lens, is ready to finance the Owls' bid to get back into the Premier League.

Bullen, 43, who also coaches the club's Under-21s, has welcomed the takeover, but accepts he faces an uncertain future.

"Going forward this is an ex citing time for the club, but I'm not naive and with change comes further change," Bullen told Press Association Sport.

"So I'm a little bit nervous. There's a certain amount of trepidation because when a new owner comes in you never know what's going to happen until he has spoken to everybody.

"But whatever happens I have no doubts Stuart deserves the opportunity to sit down and share his views with the new owner.

"Stuart will have a meeting with him. He's out of the country at the moment.

"He offered to fly back immediately, but there's still various bits and pieces to be sorted out I understand before the Football League can ratify the takeover.

"So that meeting will happen, but until then there's uncertainty and that's understandable.

"Someone putting in £40million deserves the opportunity to make some changes.

"But I would say the way things have gone that Stuart has done more than enough to be given his chance."

Former Owls skipper Bullen, who led the club to promotion from League One in 2005, is waiting to learn whether he can continue alongside Gray.

"I've learned such a lot with Stuart during our seven or eight months working together," he added.

"He's very much a players' manager and a coaches' manager. He shows a lot of respect to the people he works with.

"But we all know that until discussions have taken place certain things will remain unclear."
