Southampton are in talks with Sporting Lisbon to sign midfielder Mateus Fernandes, 20, for a fee worth up to £16million.
The Saints got their Premier League camapign underway on Saturday afternoon following promotion back to the top flight last season, but lost 1-0 against Newcastle.
Despite being down to 10 men for the majority of the match, the Magpies impressed and stood firm against a dominant Saints side to take the three points.
It was a disappointing afternoon for Russell Martin's side, but there may be better days on the horizon in the form of the new signing to help things.
