"It's true that Defoe definitely helps the team when he comes on," said Ramos.
"But I have four centre forwards I have to choose between. He's one of them.
"Obviously we now only have three forwards to choose from so the minutes will get shared around - mathematically he has more chance of playing.
"There's no one, two, three or four in order. We simply have four centre-forwards to play in two positions, so two can play each game and two have to sit it out."
The win puts Spurs up to 13th in the table after a series of late goals cost them points in recent games.
"We've lost some very important points in last minutes of games, or in injury-time," added Ramos.
"We hope this is a turning point which gives us an impetus to go further up the table."
