Michael Beale has revealed Rangers are "ahead of schedule" with their transfer business.

The Ibrox boss made the summer claim after Sam Lammers became his fourth signing of the summer window.

Dujon Sterling, Jack Butland and Kieran Dowell had already agreed on moves to Rangers as part of Beale's summer rebuild.

And with striker Lammers, 26, now in the building Beale has admitted the club are further along with their plans than expected at this stage.

However, that doesn't mean business is done for the summer with the Ibrox boss insisting there will be more trading in and out in the close season.

Discussing the transfer business so far, Beale said: “I am delighted with our progress so far in this summer transfer window.

"We have worked extremely well to recruit Jack Butland, Dujon Sterling, Kieran Dowell and Sam Lammers.

"We are ahead of schedule in our plans.

“The coming weeks will see more trading both in and out of the squad as we prepare for the season ahead."

Teasing further signings in the near future, Beale added: "We have key areas of focus and we are close to securing our targets in those positions.” 

And commenting on Lammers' arrival - in a deal worth more than £3million - Beale added: “Sam is a player I have been aware of for a number of years.

"I first knew him as a young player at PSV and have followed his career closely from afar and he excelled in Holland both in the Eredivisie and the under-21 national team. 

“Sam will give us great technical and tactical quality, being able to play in a variety of attacking positions as a number 10 or nine.

"He was the first player I met with as part of the planning for the new season and during our lengthy discussions, it was clear that we share the same ideas on football and on his personal development moving forward. He has a strong alignment to the other players in our squad. 

"Having recently turned 26, he brings a wealth of experience having already played in the top leagues in Holland, Germany and Italy. We are delighted he is joining us at Rangers and I’m looking forward to working closely with him."
