Middlesbrough are looking to bolster their defensive options with the signing of Ipswich’s Jonas Knudsen and Tomas Kalas.
Knudsen, who is also interesting Championship rivals Stoke, is wanted by Pulis to bolster his left sided options having sold Ben Gibson to Burnley.
The Danish international, who comes with a Pulis-liking long-throw, is now set to depart Portman Road by the deadline on Thursday with Boro hoping to do a deal for around £3million, but they may have to go higher.
They also want Kalas – who has already enjoyed a stint on-loan from Chelsea at The Riverside during Aitor Karanka’s era.
The Czech star spent last season on-loan at Fulham, but a move back to Craven Cottage looks unlikely and Boro are ready to step in with a loan deal.
Should a deal for Knudsen or Kalas fail to come off, then Boro have also asked Rosenborg about Birgir Meling – who can play across the back-four.
Meling is a player Boro know quite well, given he spent two years with the club as a youth player before heading back to Scandinavia.
The 23-year-old is now a full Norwegian international, and joined Rosenborg last year.
