For so long, Spurs looked like Leicester City's closest challengers, but the wheels came off their campaign in spectacular fashion as Arsenal pipped them to second spot after Mauricio Pochettino's side lost 5-1 at relegated Newcastle on the final day.
Indeed, Tottenham, who finished 11 points behind champions Leicester, appear to have one of the strongest first XIs in the division, and Merson says Pochettino need only beef up his troops with adequate squad players in order to go all the way next term.
"If someone said you'd have a bet on someone now, I'd go Tottenham," he told Sky Sports' Fantasy Football Club podcast. "They need another centre-forward, just incase Kane gets injured.
"But they have their team. Everybody else [doesn't]. Arsenal need four players. Manchester United need four or five. Liverpool need four or five. Manchester City and Chelsea need four or five.
"Tottenham don't. They need squad players. They don't need to buy anyone to go straight into the team."
Arsenal, it seems, have already bolstered their team in preparation for next season following reports that they are on the brink of signing £34 million-rated midfielder Granit Xhaka from Borussia Monchengladbach (ESPN).
Liverpool will also expect a busy summer in what is set to be Jurgen Klopp's first transfer window as Reds manager, having replaced Brendan Rodgers back in October.
It will be difficult for Tottenham, and Liverpool and Arsenal, of course. Chelsea and Manchester City will definitely have new managers in the form of Antonio Conte and Pep Guardiola, while Manchester United might well be welcoming Jose Mourinho to the Theatre of Dreams, according to BBC.
