Transfer Talk: Hit and miss for Boro | Rotherham get their man

Paperwork is still to be completed but 30-year-old former Manchester City forward Negredo has already linked up with Boro at their pre-season training camp in Marbella.

The promoted Teessiders were also poised to sign Serbian centre-back Subotic from Dortmund, until the Bundesliga club announced he had failed a medical.

“Bad news for Neven Subotic,” a BVB statement read. “The investigation of a specialist in England has shown that the Borussia Dortmund player must undergo surgery in the rib area. It is expected that Subotic will be out for the rest of the year.”

The former Serbia international won the league with Dortmund in both 2011 and 2012.

Negredo, meanwhile, was a member of the City side which won the Premier League title in 2014.

The Spain international impressed at the Etihad Stadium, scoring 23 goals in 49 appearances in what proved his only season at the club after a £16.4m move from Sevilla in 2013.

He returned to Spain with Valencia in the summer of 2014, initially on loan before a £19m permanent deal was agreed last year.

He boasts 112 goals from 264 appearances in La Liga and was also a member of Spain’s victorious Euro 2012 squad.

It has been a busy summer for Boro manager Aitor Karanka with Antonio Barragan, Victor Valdes, Viktor Fischer, Bernardo Espinosa, Marten de Roon and Jordan McGhee already on board at the Riverside Stadium.

Rotherham United’s summer-long pursuit of Jake Forster-Caskey has finally paid off after the Brighton & Hove Albion midfielder moved to the New York Stadium on a season-long loan deal.

The 23-year-old spent part of last season at MK Dons after falling down the pecking order.

“Jake is a very talented footballer,” said Stubbs. “He is one we have been trying to get done for a number of weeks now. It has took a little bit of time but I am pleased that we have managed to eventually get it over the line.”

Forster-Caskey, a former England Under-21s international, is the Stubbs’ third signing.
