Spain's world number one Carlos Alcaraz says he "does not feel the best player of his generation" after beginning his Wimbledon campaign with a victory.

US Open champion Alcarez, 20, is aiming to become the third youngest player to win the men's singles title and beat veteran Jeremy Chardy 6-0 6-2 7-5.

"There are a lot of great players in my age there right now - we are going to share great moments," said Alcaraz.

His match was one of only a few to finish on a rain-affected day two.

There was no play on the outside courts from just after midday because of the poor weather, with only the matches on Centre Court and Court One - the two courts with roofs - completed on Tuesday.

Alcaraz impressed, dropping only seven games and needing less than two hours to defeat 36-year-old Frenchman Chardy, who was playing the last competitive singles match of his career.

As well as his US Open win, Alcaraz reached the semi-final of the French Open in May, losing to 23-time Grand Slam champion Novak Djokovic.

Asked if he felt he would be the successor to the Serb, Alcaraz highlighted 21-year-old Italian Jannik Sinner and 20-year-old Dane Holger Rune, ranked eighth and sixth in the world respectively, as other options.

"I don't feel I'm the best of my generation," said Alcaraz.

"Sinner is there. Rune, as well. They are playing a great level.

"It's 1-0 head-to-head against Rune, he's up on me right now and I've had great matches with Jannik."

Eight-time Wimbledon champion Roger Federer retired in September and was watching on from the Royal Box on Centre Court, with Alcaraz disappointed he did not see his match on Court One.

"I saw that Roger Federer was here and I was a little bit jealous," added Alcaraz. "Honestly, I want Roger Federer to watch one of my matches obviously.

"I wish to talk a little bit with him and for me it would be amazing so I hope to see him around more than once."

Retiring Chardy swept aside by impressive Alcaraz

Chardy reached the last 16 in 2014 and has already said Wimbledon would be the last time he plays in a singles tournament in his career.

He was playing at Wimbledon for the 14th year and has been as high as 25th in the world rankings.

"He's a different generation because I'm close to double his age," Chardy told the ATP Tour website before the match.

"For me it is an emotional week because it will be my last tournament in singles so it is a gift to have the chance to play against him."

Queen's champion Alcaraz is aiming to become the third youngest player to win the men's Wimbledon singles' title in the Open Era, behind 17-year-old Boris Becker in 1985 and 20-year-old Bjorn Borg in 1976.

His performance in the opening two sets was near-flawless with Chardy struggling to contain his opponent's serve and producing a number of double faults at key moments.

Alcaraz needed only 22 minutes to take the first set and broke Chardy's serve in the opening game of the second as the victory looked to be a formality.

Chardy did finally get a game on the board by winning the fourth game of set two, receiving a superb reception from the Court One crowd for doing so.

At two sets down, Chardy restored some pride in the third set and managed to break Alcaraz's serve in the sixth game, only for the Spaniard to instantly get the match back on serve a few minutes later.

Alcaraz then broke in the 11th game and served out the win to set up a second-round meeting with another French player - either Alexandre Muller, 84th in the world, or Arthur Rinderknech, two places higher at 82nd.

"I played really well and at the beginning of the match in the first set he was in a little bit of trouble," said Alcaraz.

"I'm really happy to play at a great level and to get through. It's really beautiful to play here and I'm really happy to have a lot of people supporting me.

"The main goal for me this tournament is to win it."
