Antonio Conte has unwittingly experienced his first taste of Tottenham Hotspur's rivalry with Arsenal by falling foul of a Gunners fan's prank on Instagram.
The highly-rated Italian was appointed Spurs manager on Tuesday after chairman Daniel Levy promptly sacked and replaced Nuno Espirito Santo following Saturday's 3-0 defeat by Manchester United.
Conte has vowed to play "attractive football" and bring consistency to a club characterised by turbulence under Nuno and his predecessor, Jose Mourinho.

The 52-year-old took charge of training for the first time on Tuesday afternoon and he has been active on social media following his unveiling.
Conte has re-posted dozens of Instagram stories welcoming him to the Tottenham Hotspur Stadium - but one deceptive post appears to have slipped through the net.

The unsuspecting manager, or indeed his media team, shared a story from supposed fan, 'conte18900', showing a picture of him holding a Tottenham shirt with the caption: "Good luck @antonioconte."
Unfortunately for the former Juventus, Chelsea and Inter Milan boss, he failed to realise the story was accompanied by a famous Arsenal chant.
Upon opening the post, Instagram users were met with a chorus of: "Arsenal FC, we're by far the greatest team the world has ever seen."
It appears the fan was aiming to catch out the new Tottenham manager and it certainly looks as though he succeeded.
However, social media pranks are the least of Conte's worries as he looks to address Tottenham's concerning form and bring with him a much-needed 'new manager bounce'.
Spurs have lost five of their last seven Premier League games and were beaten 1-0 by minnows Vitesse to leave their hopes of advancing in the Europa Conference League hanging in the balance.
Conte's first task is a home clash with the Dutch club this Thursday before a trip to Everton on Sunday afternoon.
"I have seen on Tuesday the training ground and I want to start work," he said.

Conte has an excellent CV which includes league titles from his time in Italy and England, but he insists his focus is on his "new challenge" in north London.
"My past, what I did with previous clubs, is important," he added. "I'm proud. For me, the new challenge is Tottenham. I want it to become an important part of my career as a manager."
