Guardiola heaps praise on Laporte but acknowledges the defender can't fix all Man City's problems.
Pep Guardiola was delighted Aymeric Laporte returned to Manchester City's starting XI during midweek, but the Spaniard knows the France international won't solve all their defensive woes.
Laporte returned to action - after almost five months on the sidelines - in City's narrow 1-0 win to Sheffield United at Bramall Lane on Tuesday evening.
"He played more than 70 minutes in his first game," Guardiola said of the Les Bleus star who required surgery after damaging his cartilage and lateral meniscus in Man City's home win against Brighton on August 31.
"He played well but he is not going to solve all our problems. He is one more player we can use.
"He's a guy who helps with our build-up, he helps us keep the ball better and because of that we are not as vulnerable to counter-attacks.
"He's strong in the air, fast and has a special personality. His attributes can help us be a better team. When we play good we don't need him, and that's happened most of the time this season."
