Mbappe and Haaland the successors to Messi and Ronaldo, claims Higuain

Both players have been linked with moves to Real Madrid, and Mbappe recently scored a superb solo goal to give Paris Saint-Germain a 1-0 lead over Los Blancos in their Champions League round-of-16 tie.

Madrid had multiple bids for Mbappe turned down in August. The 23-year-old will become a free agent at the end of the season.

Reports had suggested that Mbappe could miss Wednesday's return leg in Spain after suffering a knock in training, but with PSG hoping that he will be fit for the trip, former Madrid forward Higuain claims the forward is one of the two heirs apparent to Messi and Ronaldo.

The Inter Miami forward, who scored 107 goals in 190 LaLiga appearances for Madrid between 2007 and 2013, also believes Mbappe's arrival could take his old club back "to the top" of European football.

"[Mbappe] has all the characteristics," Higuain told Stats Perform.

"I believe that Leo and Cristiano at some point will stop playing, because life is like that, and Mbappe and Haaland will be their successors.

"Of course, Mbappe has all the characteristics to take Real Madrid to the top."

Mbappe recently moved level with Zlatan Ibrahimovic as the joint-second highest goalscorer in PSG's history, with his tally of 156 goals for the French giants bettered only by Edinson Cavani, who scored 200 goals for the club.

Madrid boss Carlo Ancelotti called Mbappe "unstoppable" after he downed the Spanish giants at the Parc des Princes last month.

PSG sporting director Leonardo, meanwhile, recently referred to Mbappe as the "best player in the world today", hinting the in-demand striker could yet elect to remain in the French capital.

Mbappe was suspended for PSG's 1-0 Ligue 1 loss to Nice last time out, and is the only player in the French top flight to have reached double figures for both goals and assists this season, with his 24 goal contributions (14 goals, 10 assists) helping the Parisians to a 13-point lead at the summit.

Haaland, meanwhile, is one of the most prolific forwards in European football, and it has been reported that Madrid and Manchester City are leading the chase for the 21-year-old.
