"Thank you, Arsene Wenger, for your legacy", he said. Arsenal have been looking for a new coach for the first time in over two decades since Wenger announced last month he was stepping down at the end of the season.
New Arsenal head coach Unai Emery believes he already has the players at his disposal to challenge for major honours.
Wenger won three Premier Leagues and a record seven FA Cups during his time in charge, his crowning glory coming in the 2003/04 season when Arsenal won the league without losing a single game.
"I am thrilled to be joining one of the great clubs in the game", said the new Spanish boss.
Unai Emery may have come up on the rails to land the Arsenal job - but springing surprises is certainly not one of the Spaniard's traits.
'I have met Stan and Josh Kroenke and it's clear they have great ambitions for the club and are committed to bringing future success. We spoke about all they want and I want to work together, on this club, this responsibility.
Emery did not disclose what his plans are for the Arsenal squad in terms of transfers, but said that "all the players, for me, that I want" will remain with the team.
Emery was appointed to replace Arsene Wenger, who left the club at the end of the season following 22 years in charge, with the 46-year-old tasked with improving on a sixth-placed Premier League finish last season. "His hard-working and passionate approach and his sense of values on and off the pitch make him the ideal person to take us forward".
'We conducted a confidential, wide-ranging and rigorous search involving extensive background references, data and video analysis, and personal meetings with all the candidates we shortlisted.
The main worry for Arsenal fans might be Emery's ill-fated spell with Spartak Moscow in 2012 and his failure to fulfil his mandate at Paris Saint-Germain, where he was asked to win the Champions League after moving to the big-spending French giants in 2016.
European Coach of the Season: 2013-14.
"I speak with a lot of coaches, those are private conversations, but now that I am here, all information is welcome".
He also said he wants to keep the same brand of attacking football that was Arsenal's hallmark under Wenger - but hinted that he'll demand more pressing without the ball from his players.
Guardiola and Emery faced each other during their respective Barcelona and Valencia tenures, with the latter going on to Sevilla and a glorious run of three consecutive Europa League triumphs.
