The Chilean has not enjoyed his best form, but Fabregas insists he can be counted on.
The Chilean has been a big hit in his first two seasons at the Emirates following a big money move from Real Madrid in 2014.
He has quickly established himself as one of the stars of Arsene Wenger’s side, despite what has arguably been a disappointing season overall for him.
Indeed, he has come in for criticism in recent months as the Gunners have fallen away in the title race.
Fabregas though, says that his former Barcelona teammate is a man that you can always count on.
“I think he fits perfectly well into the Premier League,” he told Monday Night Football. “The way he carries the ball, he’s so hungry, he’s a leader and a goalscorer and technically gifted.
“He always gives his all and is very humble. He can have better days, but you know he’s a guy that you can count on.”
For now, Arsenal fans will be hoping that Sanchez can find his best form between now and the end of the season.
They will certainly need him, as well as Mesut Ozil and several others, at their best with their hopes of finishing in the top four very much at risk.
Manchester United are breathing down their necks in fifth and the Gunners will not be able to afford any slip-ups as the campaign draws to a close.
