They remain pointless away from home in 2018 ahead of Sunday's Premier League finale - and Wenger's last game in charge - at Huddersfield and have lost seven straight top flight away matches for the first time since 1966. "It's these contradictions I don't understand and would like to know better", Wenger added.
"I enjoyed some aspects of it, yes - and not all", he said.
"The European League will happen and it will be soon because it's a way for other clubs to fight against the financial power of the Premier League".
Wenger says the hugely disappointing defeat to Atletico Madrid in this season's Europa League is another major regret from his time as Arsenal manager.
"This team and I would like to thank everybody, especially my backroom staff, my players, all the supporters and (chairman) Dean (Hoyle) and the board as well for all the support and help they gave us".

"It's a bit odd for me [that it's his last news conference]". But as well I would say to respect what has been built here and what people care about. "I will try to do my job until the last minute I work here, and then think about the future".
And Wenger believes addressing the team's issues on the road could pave the way for a title challenge under his successor.
However, they won't want to leave the season on a sour note, as their 3-1 loss away to Leicester means that they still have not picked up a single away point in the new year. "I think that is the next step we will see".
