Watch Ajax vs Juventus Live StreamingWith regular number one Manuel Almunia set for a spell on the sidelines because of a finger injury, Fabianski, 24, will get another opportunity to stake his claim.
The young Pole, out earlier in the season after knee surgery, has seen Italian Vito Mannone emerge as a genuine challenger for the long-term goalkeeper's jersey at the Emirates Stadium.
Fabianski may have been somewhat exposed on his last outing during the FA Cup defeat at Stoke but Wenger has complete faith in his stopper.
"I believe that Fabianski is top, top level and has massive potential," said the Arsenal boss.
"It is not easy for a keeper to come in and out.
"What he misses at the moment is the number of games but I have no doubt about his potential."
