Arsenal legend Thierry Henry has claimed that Chelsea boss Jose Mourinho holds a psychological advantage over Arsene Wenger.
Wenger is yet to record victory over Mourinho's Chelsea in the Premier League, with the Portuguese claiming seven wins and five draws from their 12 games played.
Ahead of Sunday's meeting between the pair at the Emirates, the Gunners' all-time record goalscorer Henry admitted that Mourinho has the edge over his counterpart.
"[Arsenal v Chelsea] is the game Mourinho loves the most," Henry told Sky Sports News. "Before he arrived [in 2004], I remember Chelsea couldn't beat us, they just couldn't.
"Mourinho came and if I can say, he got into Arsene's head and his game. He doesn't mind not having the ball and that suits his game perfectly, because Arsenal will have the ball and the belief that they can win.
"Mourinho is going to tell his team to sit, and wait for a mistake and take advantage."
Victory for Arsenal will close the gap on the Premier League leaders to to seven points.
