Portsmouth pair Gary O'Neil and Matthew Taylor have agreed long-term deals with the club.
O'Neil and Taylor are both tipped for great things
Midfielder O'Neil has signed a five-year contract, with Taylor, who plays as a left wing-back, accepting a four-year agreement.
Manager Harry Redknapp said: "I'm delighted Gary and Matty have pledged their long-term futures to Pompey.
"This shows our commitment to building a top squad of players which will be part of this club's exciting future."
O'Neil, 23, became the youngest player ever to play for Portsmouth when he made his debut in January 2000 and is now the longest-serving player at the club.
Taylor was signed by Redknapp for £400,000 from Luton in 2002, during the manager's first spell at Fratton Park.
The 24-year-old has since firmly established himself in the first team, making 130 starts.
Redknapp told the Portsmouth website: "We intend to be a match for the best clubs in this league - and for this we need to keep hold of our best young and talented players.
"Gary and Matty have both earned the rewards and are poised to continue to work hard and be up there amongst England's finest."
