Tony Pulis is hoping to tie up 'one or two' new signings before the start of the Championship season.
And a new striker is thought to be top of his wishlist - although the Boro boss will only make a move for the 'right' type of player.
Aiden Flint and Paddy McNair have already arrived at the Riverside Stadium this summer as Pulis opts for a process of evolution over revolution.
He is keen to add some more quality to a squad that came agonisingly close to promotion back to the top flight last season, and his first two additions represent a good start.

But Pulis is keen to press on and secure more additions, provided that they are a good fit for his side.
It is understood that his primary focus is signing a new striker, with several names already linked with a switch to Teesside.
Ipswich striker Martyn Waghorn has been heavily rumoured to be interesting Pulis, although his current club will demand a large fee.
Sam Vokes and Peter Crouch have also been mooted - as well as several others - but the Middlesbrough manager is prepared to bide his time ahead of the window closing on August 9.
“We need to get one or two players in, that’s important," he admitted.

"But we’ve got to make sure they are the right players.
"We’d like to bring one or two others in if they are available and if we can.
“Sometimes you have to wait a little bit and see what happens and see what spins around.
"We’ll see how it goes – we’ve got three weeks to get a few deals done.”
