Manchester City have agreed a potential British record transfer fee to sign England midfielder Elliot Anderson from fellow Premier League club Nottingham Forest, according to several media reports on Thursday.
Britain's Press Association and the BBC reported that City had agreed a fee which could rise to £130 million for the 23-year-old.
The current highest transfer fee paid by a British club was the £125 million Liverpool spent to bring Alexander Isak to Anfield from Newcastle last year.
Forest had reportedly rejected two previous offers from Man City for Anderson.
He is currently in the United States with the England World Cup squad, but the move could be officially confirmed before the end of the tournament.
"It's about common sense. I would not like (it) on the day before a match, or on a matchday, that's the policy," said England manager Thomas Tuchel when asked about transfers being completed during the World Cup.
"If it's done privately, efficiently and quietly, then we are always happy to help. It helps to have clarity around any player."
England face Panama in their final Group L game in New Jersey on Saturday, by when they may already have been assured of a place in the last 32.
Anderson started both their opening 4-2 win over Croatia and the subsequent goalless draw with Ghana.
Man City finished second behind Arsenal in the Premier League last term in Pep Guardiola's final season in charge, but won the FA Cup and League Cup titles.
Forest were embroiled in a relegation battle for much of the campaign before a strong late run of form saw them finish safely in 16th place.
