At this stage of the season, as important as it is to be able to play your best players, concessions also have to be made so they do not burn out.
That is where having some good young players around the squad can prove useful. They can come in and give you a game or two's good work. Maybe they will give you a reason to stick with them, but if not, pulling them out after is not as much of a possible headache as with more established members of the squad.
Unfortunately for Tottenham, they have loaned out several such players. Good as the experience is they might be getting, Villas-Boas might be ruing his decision to send out a player like Andros Townsend right now.
One youngster who is still around is Tom Carroll. The midfielder put in a decent second-half showing against Fulham after coming on for Moussa Dembele in the latest in a line of cameo appearances that have shown him not to be out of his depth at this level.
Now, that is different to him being ready to be a fully fledged starter. Carroll has been promising enough to warrant more of a look though. Spurs could benefit from his movement and eagerness to get on the ball as a real outlet in their more staid outings. His eye for a pass does not put him out of place either.
Right now he would serve the added purpose of being able to give someone else a rest and perhaps a reason for them to come back eager to reassert their own claim to be playing.
