The bench is playing a key role in Barcelona's revival under Xavi

Barcelona strengthened in attack in the January transfer window and the results are already being seen. There is finally internal competition and that's helping Xavi Hernandez's side in a number of ways. One way was once again on show on Sunday in Elche, when two substitutes scored the goals as Barça came from behind to win 2-1.

Ferran Torres came on at halftime and scored the equaliser on the hour mark and Memphis Depay also came off the bench to win and score the penalty that sealed the three points. The Dutchman had come on in the 75th minute.

Barça's last five goals have now been scored by substitutes. Ousmane Dembele, Luuk de Jong and Memphis all scored after coming on in the win over Athletic Club last weekend.

Prior to that, Luuk e Jong had played a key role as a game-changing substitute, scoring the equaliser at Espanyol late into stoppage time after being thrown on late on.

With the new substitutes, Xavi now has a range of options and depth. In addition to those mentioned, he also has Adama Traore who is setting up goals and Pierre-Emerick Aubameyang who has already scored four goals since joining from Arsenal.

Meanwhile, Martin Braithwaite did not even make the squad for Sunday's game due to the options at Xavi's disposal. "I feel bad," the coach said.
