CHELSEA are boosted by the return of Ashley Cole and Gary Cahill for tomorrow's Europa League semi-final.
The Blues defensive duo have missed the past three weeks through injury, but travelled to Switzerland and trained today ahead of the first-leg clash.
Benitez is set to shuffle his pack again following the 2-2 draw at Anfield on Sunday.
“Obviously fatigue when you play so many games and travel around Europe is a key factor to consider,” said the Spaniard.
“I praise my staff because we try to manage the squad in the best way possible. Still the team is [playing] good games and we have fresh legs in some players.
“We have to rotate, change and manage players.”
Fernando Torres will continue in attack, with Demba Ba cup-tied, while Oriol Romeu (knee) is a long-term absentee.
Basel beat Spurs on penalties in the last round, and Benitez is wary of the threat posed by the Swiss side.
He added: “They've worked very hard, have played well, and are well organised. They press well and play good counter-attack.
“They have good players with pace and ability so we will have to do really well if we want to win.
“Philipp Degen was my player [at Liverpool] and is a good professional, a worker and enjoys playing football. They have some good young players and others with more experience.”
