Wenger left the north London club at the end of the 2017/18 campaign after 22 years in charge of the Gunners.
During that time he won three Premier League titles, including an unbeaten league season with his ‘Invincibles’ side of 2003/04, and seven FA Cups.
He returned to the Liga club earlier this year after a less successful spell at Roma, and pointed to Arsenal as an example that results don’t always reflect behind-the-scenes work in a long interview with El Confidencial.
“Of course, football’s problem is that everything is based on results,” he said.
“But there are projects that consolidate their future in the present with good selling policies, talent retention, academies.
“Sometimes they only get the attention when they get results, but they aren’t valued in the moment.
“The example of Arsenal is a very good one. They are a pioneer club that invested in data, bought their own ‘app’ five or six years ago and are developing it.”
The Gunners are currently third in the standings and in the midst of an eight-match unbeaten run in all competitions.
