Stoke have completed the signing of Robert Huth from Middlesbrough and he could be followed to the Britannia Stadium by Boro striker Tuncay Sanli.
The 25-year-old defender has finalised personal terms after undergoing a medical, after Middlesbrough manager Gareth Southgate confirmed that the Boro pair had been in transfer talks with the Potters.
Stoke announced the Huth deal to be worth £5m, which could rise to £6m, and it breaks the £5.5m record that they paid to Reading for Dave Kitson.
Huth, who is hoping to win a place in Germany's World Cup squad, said: ''I am grateful to Stoke for the opportunity to play in the Premier League so soon again. It was really a no-brainer to come here once I found out that this club wanted to sign me.''
The former Boro skipper has made an excellent start to the League Championship season, keeping four clean-sheets, but is understandably keen to return to the Premier League and Stoke's new assistant manager Peter Reid is a keen admirer of the big centre-back.
He said: "Robert Huth has tremendous attributes and would be a quality acquisition. I've followed his progress since he came over from Germany to Chelsea and he's a very good player.
"He's a big, powerful boy who is good in the air, and he has great feet as well. He's had a few injuries, but he appears to be putting them behind him."
Meanwhile, Tuncay, who has previously been linked with Liverpool, will add enormous attacking flair as the Potters battle to stay in the Premier League for another season.
