Watford dismiss Everton's approach for manager Marco Silva - sources
Arsenal goalkeeper Petr Cech has said rivals Tottenham must win silverware before they can claim to have become the dominant club in North London.
Cech, whose team take on Spurs in a derby on Saturday, told Sky Sports Spurs needed a trophy in order to show "progression."
Tottenham finished above Arsenal last season, the first time in 22 years that had happened, having been pipped to second place by them on the final day of the campaign before that.
But Cech, asked whether the balance between the rivals had changed, said: "No, I don't think so.
"There is always one odd year where things can change, but the most important thing for us is competing against the other teams for the Premier League title and for the glory.
"We are not competing against Tottenham Hotspur. Our target is to win the title and be successful during the season, not necessarily looking at what Tottenham are doing.
"They've been there in the last few years so now I think they have to make sure they win something to show the progression. Success is ultimately winning trophies."
And the former Chelsea goalkeeper praised Tottenham boss Mauricio Pochettino, saying he had been "the big factor" in their improvement.
"You can see from his work at Southampton that he is very capable as a manager and coach," he added.

Watford have rejected an approach from Everton for their manager Marco Silva, sources close to the Vicarage Road club have told ESPN FC.
Everton are continuing their search for a new manager following the sacking of Ronald Koeman and Silva has emerged as one of their top targets.
Watford are determined to keep hold of Silva as they look to build on his promising start to life at Vicarage Road this season and have informed Everton that any approach will not be welcome.
Sources have told ESPN FC that Silva would be interested in speaking to Everton about the vacancy at Goodison Park, but it remains to be seen if Watford would change their stance on the Toffees' interest.
Everton under-23s coach David Unsworth is currently in caretaker charge of the club and secured his first win against Silva's Watford before the international break.
Silva has done well at Watford since taking over in the summer and the club currently sit ninth in the Premier League.
The 40-year-old joined Watford after leaving Hull at the end of last season. Despite failing to steer Hull to safety from relegation to the Championship, Silva impressed in the role after replacing Mike Phelan in January.
Another target for Everton, former England boss Sam Allardyce, is also reportedly out of the running after he cooled his interest in the position as the club were only willing to give him a short-term deal until the end of the season, with the 63-year-old keen on a long-term contract.
