Fabregas has backed Messi to get back on the goal trail after a three-game scoreless run - a drought by his prolific standards - which included him missing a penalty in injury-time of the 0-0 draw with Sevilla on Sunday night.
The former Arsenal man said of the Argentinian: "Messi is the best and a born winner.
"Messi always wants to score goals, but that did not happen on Wednesday (against Granada).
"However, the great thing about football is that the best players take no time in getting back on their feet.
"On Saturday he will have another chance to prove that he is the best."
