City have been in negotiations with the Brazilian club for a number of weeks and, after some resistance, have finally made a breakthrough in talks which the Premier League club believe will lead to 19-year-old Reis eventually joining them.

Palmeiras had hoped to keep Reis for next summer’s Club World Cup.

However, City sources believe if the deal, which is reported to be for £29.4m, is eventually concluded, Reis will join them immediately.

A Brazil under-17 international, Reis has made 18 league appearances for Palmeiras.

A right-footed central defender, it is intended Reis will form part of a reshaping of Pep Guardiola’s squad that is also planned to include Lens defender Abdukodir Khusanov, while talks are continuing with Eintracht Frankfurt over a deal for striker Omar Marmoush.
