Kylian Mbappe must be afforded time to understand his new Real Madrid role, with differing challenges posed compared to his success with France and Paris Saint-Germain.

Former Argentina international Mario Kempes believes Mbappe will not have faced an experience like the pressure that comes with playing with Madrid.

The France captain has still managed seven goals in just 11 appearances to start his Los Blancos career, including finding the net five times in eight LaLiga appearances.

Yet Kempes, a 43-cap Argentina international, says Mbappe will have to adapt after what he sees as easier challenges when playing for France and Ligue 1 giants PSG.

"I can't talk about being a number nine, because I've never been one. I think it's all a matter of getting used to it, because Mbappe isn't going to come in and score 40 goals," Kempes told Stats Perform at Festival dello Sport in Trento, Italy.

"It's different to play in France or in the national team, it's nothing like playing in Madrid. At Madrid, you have to play 11 players or more every game and sometimes the ball doesn't go in or hits the post."

Mbappe scored 27 times in 29 league appearances for PSG last term, as well as eight goals in 12 Champions League outings.

He has taken to life in Spain with ease, too, also managing five LaLiga goals in September – a tally no player could better last month across Europe's top five leagues.

The 25-year-old has since opted to sit out of France's October internationals with Israel and Belgium, despite declaring himself fit to play for Carlo Ancelotti's side.

That has caused backlash from some supporters in France and former players after Mbappe made his focus clear on his intentions with Madrid, and his sights on a first Ballon d'Or.

His success with Madrid will be dictated by the relationship with his team-mates, says Kempes, who expects Mbappe to need time to impress in the Spanish capital.

"You also have to get to know your team-mates," Kempes added. "They are young and have a lot of desire and are very good, you also have to get to know each other on the pitch.

"There is still a long way to go."

Mbappe and Madrid return to domestic action on Saturday when they visit Celta Vigo.

Lionel Messi remains in control of his 2026 World Cup destiny with fitness no issue due to the lesser demands of playing in MLS.

That was the message from former Argentina international Mario Kempes, who expects Lionel Scaloni's superstar attacker to be physically capable of featuring in FIFA's next tournament.

Doubts remain as to whether Messi will make it to the tournament hosted across the United States, Mexico and Canada, where he will hope to play aged 39.

The former Barcelona star is already playing in the USA's domestic competition, though, and Kempes believes that could have a significant influence on him featuring at the World Cup.

"I think Messi will arrive in good shape and fresh, because the MLS is not really very demanding, even though he demands himself," Kempes told Stats Perform at Festival dello Sport in Trento, Italy.

"I think he will arrive in good shape, but first we have to wait for the qualifiers and see how he feels because he is the one who will decide if he is in condition to come in and contribute everything he knows."

The eight-time Ballon d'Or winner suffered an unfortunate ankle injury in the 2024 Copa America final but has since returned to the international fold.

Messi missed several MLS matches for Miami, with that absence allowing him to recover in time for Thursday's 1-1 qualifying draw with Venezuela.

Such management of fitness issues could be key for Argentina's Messi-led hopes at the next World Cup, where he will hope to add to his 13 goals at the tournament.

Only Gerd Muller (14), Ronaldo Nazario (15) and Miroslav Klose (16) have managed more strikes at the World Cup, with Messi out for further history if he makes the 2026 edition.

Having scored seven goals en route to Argentina's 2022 success, Messi will have no doubts of adding to his impressive tally, though Kempes urged caution for expecting him to be available.

"You never know what can happen because there is still a long way to go," Kempes, who appeared 43 times for Argentina, added.

With or without Messi, Kempes has been impressed with Scaloni's work in transforming Argentina's fortunes, winning two Copa titles as well as FIFA's top prize.

"Scaloni has already surprised us all when he takes over the national team and changes all the players except for [Nicolas] Otamendi, [Angel] Di Maria and Messi," Kempes continued. 

"I think he has made a generational change that has not been noticed, because he mixed the players who were already there with the new ones.

"And the new ones have been very well received and have that winning mentality that led Argentina to win two Copa Americas and a World Cup."

Argentina wrap up their October internationals when they host Bolivia on Wednesday, aiming to extend their three-point lead at the top of their qualifying group.
