Arsenal manager Mikel Arteta has praised Dundalk counterpart Filippo Giovagnoli's recent rise from obscurity to a head coaching position as a "great story".
The SSE Airtricity League side visit the Premier League giants for a Europa League group stage fixture on Thursday.
Facing Arteta - a relative novice as a manager in his own right - on the Emirates Stadium sideline will be Giovagnoli, who had never managed a senior side before his surprise appointment as Lilywhites boss in August after the club had parted ways with Vinny Perth.
"I think it's a great story," the Arsenal boss said of Giovagnoli.
"It was a good one to hear. I watched a really long interview of his because I wanted to know who [he] is and what he is trying to do and what he is trying to express to his players and this is how I found out what had happened.
"But straight away he said that he could feel that the players believed in what they were doing which is everything that coaches want and I think they have created a really good chemistry with that team. Big merit to them for the work that they are doing."

Arteta added that "the unity of the team" was the main strength Dundalk possess, with "how hard they work together and how well they are organised".
"And then there are a few bits where they look really dangerous," he continued, pointing out set pieces as another threat Dundalk can pose to his Gunners side.
"I'm sure they have prepared them for tomorrow and we will have to control normal aspects that we have to do every week."
The Arsenal boss has just two fit recognised central defenders available for their Europa League Group B encounter.
Shkodran Mustafi and Gabriel Magalhaes are his only options, with David Luiz (thigh), Rob Holding (hamstring), Pablo Mari (ankle) and Calum Chambers (knee) all missing through injury.
Fellow defenders Sokratis Papastathopoulos and William Saliba are unavailable having been left out of the Europa League squad as Gabriel Martinelli (knee) also misses out - but Willian and Bukayo Saka should be in contention.
Arsenal provisional squad: Leno, Runarsson, Bellerin, Maitland-Niles, Gabriel, Mustafi, Kolasinac, Tierney, Saka, Ceballos, Elneny, Partey, Willock, Xhaka, Nelson, Pepe, Smith Rowe, Willian, Aubameyang, Lacazette, Nketiah.
