Redknapp was upset after his basement boys were held to a 0-0 draw by Norwich on Saturday.
But he said: “I have not brought players in here who are s***.
“Samba should be playing for a top-four team, so if it does not go well, the club will get £12m for him.
“Remy for £8m, if he can score a few goals, he will be £12m. The two kids from Spurs, one was three grand (a week) and the other doesn’t come to a lot of money.
“The club’s invested but they will get their money back.”
