Tottenham boss Antonio Conte has warned his players today's opponents Arsenal are much improved on last season.
Spurs hammered Arsenal 3-0 in May to pip them to Champions League football but the Gunners strengthened over the summer with the additions of Jesus, a Spurs target, and Zinchenko from champions Manchester City.
Conte, who has said he needs "time and patience" to turn Spurs into winners, believes Arsenal a good example of what happens when a manager is properly backed.
"They're a club who backed Arteta over the years. And you're seeing [what happens] when you trust a person," Conte said. "Arsenal showed this also in a tough period with Arteta, backing him in every moment, now they're having good results.
"Last season, don't forget they were in the Champions League [places going into] the last three games. They've had a good step, I think this season they're better than last season.
"They made good signings, especially Jesus and Zinchenko from a club like Manchester City, two players that are used to winning and having a winning mentality.
"It's important because I can see they've improved the level. Not only the quality but the mentality at Arsenal. I think they're doing a good job."
