Just like many other players, Benzem chose money and he joined Arabian teams when left he is getting old to earn more money there.
I think Benzema made a wise move and Real Madrid should now hire an alternative player for this position. Mbappe is the first priority and I guess Mbappe can fill Benzema's position at Real Madrid perfectly.
If Mbappe's transfer to Real Madrid takes place, a football player who will play successfully for many years as Real Madrid Benzema will be brought to the team. I believe Mbappe will outperform Benzema. What he's done for PSG is obvious and he's a perfect player statistically.
If Madrid buys Mbappe, it's clear that it will make Madrid the strongest club, especially with the arrival of Jude Bellingham and maybe some of the best players, I'm sure that next season Madrid can achieve a treble winner by bringing in great players to strengthen their squad to become a beaten team, I admit it Mbappe is such a great player that he deserves to be in Madrid as well as ahead of Benzema.
I don't imagine that if Mbappe is in Madrid and plays next season, of course they will be the most anticipated club and can also be a scary club, but according to some media, it looks like Mbappe will finish his contract with PSG and denied his move to Madrid.
