Southampton: Mauricio Pochettino cautious over transfers
Southampton boss Mauricio Pochettino will not be making any signings unless he can improve the current squad.
The 40-year-old took over from Nigel Adkins this month but is yet to add any of his own additions to the squad.
"We haven't made requests for any players but we're watching the market to see if there's any developments," he told BBC Radio Solent.
"If there was a signing, it won't be just for the sake of a signing, it will be to improve what we have already."
He added: "Overall we're very happy with our players, I think they're very capable of competing in the Premier League.
"We don't think we need any new players but if we do go for someone it will be to improve what we have already."
Pochettino spent three years managing at Espanyol before being sacked in November with the club bottom of La Liga in Spain after earning nine points from 13 games.
The Saints, who lie 15th in the Premier League, travel to league leaders Manchester United on Wednesday, a stadium which Pochettino hopes can inspire his players.
"Going to Old Trafford represents an extra motivation for us, any player enjoys playing in these mythical stadiums around the world," he added.
"We're very excited and keen to develop our game and play well.
"We all know who Sir Alex Ferguson is and what he's done in football and I'm a great admirer of his career.
"Our mentality always has to be to win and we want the squad to feel that mentality."
