Arsenal manager Arsene Wenger has warned West Ham United it could take them years to feel at home at the London Stadium.
The Gunners boss takes his side to the London Stadium for what will be the first Premier League London derby at the venue since the Hammers moved in officially in July.
The move has been overshadowed somewhat by crowd disturbances and poor performances by Slaven Bilic’s men and Wenger speaks from experience about teething problems at a new stadium.
He said: “It takes a few years, because you __have to make memories and build a little history.
"For a while, when you move from the marble hall at Highbury, it was full of history, and suddenly you move to a stadium where nothing happened before you came in there.
"You feel a bit lonely there, so you __have to rebuild the environment from the results that you had before.”
So far, West Ham have won five of their first ten games at home, although two of those were against Slovenian minnows Domzale in a Europa League qualifier and an injury-time victory in the EFL Cup against Accrington Stanley.
And Wenger, who oversaw the Gunners move into the Emirates in 2006, admitted the lack of familiarity can also impact negatively on the players as well.
“You can try, but you cannot create something artificially something that doesn't exist,” he said. “I feel as well the players know the ground, before when you played at Highbury, you kind of had a picture.
“You feel a bit like you're playing on neutral ground for a while. After that, the best way to prepare is just to focus on what we do and focus in a very strong way.”
