Tottenham are in advanced talks with Bayern Munich over the loan signing of Joao Palhinha, according to Sky in Germany.
Palhinha could now be set for a return to the Premier League, one year after he joined Bayern from Fulham for a fee worth up to £47.4m.
The 30-year-old midfielder has three years remaining on his current contract.

Palhinha made 25 appearances across all competitions for Bayern last season, including 17 outings in the Bundesliga as Vincent Kompany's side went on to become champions.
Frank: We will be active in the transfer market
Tottenham boss Thomas Frank admitted the club are "looking" for further additions in the summer transfer window.
Spurs have already secured the signing of Mohammed Kudus from West Ham, as well as Kota Takai and Luka Vuskovic.
Kevin Danso and Mathys Tel have also seen their initial loan moves converted into permanent deals.
However, Frank's side missed out on Morgan Gibbs-White after the England international signed a new three-year deal at the City Ground.
Forest accused Spurs of making an illegal approach for the midfielder with a £60m bid earlier this month.
Speaking in his first press conference since being appointed to the role, Frank commented on further incomings, saying: "There is no doubt that, if you want to compete in all tournaments, you need a competitive squad.
"There are a lot of competitive players in the squad already. The club is in the market and looking.
"What will happen, I will speak when a player comes into the building."
