Willian believes success in football does not necessarily equate to a cabinet full of silverware, highlighting Harry Kane as an example.

The Fulham attacker was a two-time Premier League winner during his time with Chelsea, and collected medals in the FA Cup, EFL Cup and Europa League.

In addition, the 34-year-old won the 2019 Copa America with Brazil and was a member of his nation's squad when they came fourth at home in the 2014 World Cup.

But when asked what defines success in football, he suggested that trophies do not solely define the legacy of a player's career.

"I think it's a mix of several factors," he told Stats Perform. "It is to win titles, [it] is to be playing at a high level.

"Sometimes there are players who don't win titles, but play at a high level and are always playing well, always scoring goals. Harry Kane, for example, for me, is a great player

"[He] is always at a high level at Tottenham, playing very well and scoring goals, but I don't think he has any career titles as a professional. Can you say that he was not successful in football?

"It depends. It is a mixture of things. It depends a lot on what it means to be successful in football. For me, the most important thing is for the player to be playing well, and the title becomes a consequence of the work."

Despite his success, Willian acknowledged there are two major honours that have eluded him, at club and international level, but he adds their absence from his collection does not detract from his other successes.

"One is the Champions League and the other is the World Cup," he noted. "Every player has that dream.

"Those are the two titles I'd really like to win, but if I don't win them, I'm satisfied with my career and the titles I've already won."

Willian has spent nine seasons in the Premier League, more than he has in any domestic top-flight competition, and he maintains it remains the strongest he has played in.

"The Premier League is the best league in the world," he added. "You'll never have an easy match.

"It might get easier during the game, and you might beat the other team, but you're never going to go into the match thinking it's going to be easy, thinking you're going to win 4-0.

"It is a very difficult league. The last one can take points from the first one, and it is very competitive and that is why it becomes the best in the world."
