Charlton live updates
Former Charlton striker David Whyte has died at the age of 43, the club have announced.
Whyte made 106 appearances for the club between 1992 and 1997, scoring 35 goals. He also played for Crystal Palace, Ipswich, Bristol Rovers and Southend.
A statement on Charlton's website read: "Charlton have been extremely saddened to learn of the death of popular former player David Whyte, who passed away on Tuesday. The former Addicks forward was just 43.
"The thoughts of everyone at the club are with David's family and friends at this difficult time."
Diego Poyet has hinted he is on the verge of completing a move to West Ham.
The 19-year-old midfielder, son of Sunderland manager Gus Poyet, is a free agent after his contract at Charlton expired.
Poyet has reportedly also attracted interest from Chelsea, Manchester City and the Black Cats.
Charlton will announce Bob Peeters as their new manager in the next 48 hours.
The 40-year-old quit as boss of Belgian side Waasland-Beveren last Thursday and will replace Jose Riga, who was not kept on at The Valley despite saving the Addicks from relegation last season.
The appointment will mark a return to south London for former Belgium striker Peeters, who had a spell playing for Charlton's local rivals Millwall between 2003 and 2005.
He led them out of the relegation zone and to an 18th-placed finish with eight wins and three draws from 17 matches.
Riga rarely used the loan players brought in by controversial owner Roland Duchatelet, which may have contributed to his departure.
Peeters will have to rebuild the Charlton squad after 11 players were released at the end of the season, while goalkeeper Ben Hamer agreed to joined Leicester.
Callum Harriott's first league goals of the season secured Charlton's Sky Bet Championship survival with a game to spare as they sank Watford 3-1.
The rookie winger opened the scoring in the first half and then put the seal on a dramatic win with a superb late strike.
There were plenty of nerves around The Valley when Troy Deeney equalised for Watford in the second half, but Charlton captain Johnnie Jackson fired them back into the lead before Harriott's clincher killed off the Hornets.
Charlton have boosted their squad with the signing of Manchester United youngster Davide Petrucci on loan.
The Italian midfielder will join up with the Addicks until the end of the season.
