Charlton chairman Richard Murray has given his backing to under-fire manager Les Reed and said the club will provide funds for new signings in January.
Reed looks despondent after the Wycombe defeat
The Addicks have won one league game in six since Reed took over from Iain Dowie and the new boss has been subjected to criticism from supporters.
Murray said: "It's unfair on Les at the moment. His current record is similar to Iain's but are both at fault?
"We will spend in January but we will have to wheel and deal."
Charlton are currently second from bottom in the Premiership but are five points from safety.
Their miserable form continued on Tuesday when they were knocked out of the Carling Cup by League Two side Wycombe Wanderers.
Some people must not look at Les but at what went on before

Murray said the signings made by Reed's predecessor may have something to do with the club's current predicament.
"Les is getting hammered at the moment and it is a tough spell for the club. Very tough," he added.
"We have to see some changes on the pitch. We were awful against Wycombe.
"But those who watch Charlton regularly will say maybe it was the same under Iain Dowie. Maybe we haven't got a good enough squad.
"We spent a lot of money in the summer - £11m we didn't have to spend.
"We backed Iain, they were his signings, but I had never heard of Souleymane Diawara, apparently the best centre-half you've never heard of.
"For a club like ours to spend £3.7m on one player like that is a fortune. Some people must not look at Les but at what went on before."
