Real Madrid's forward is very strong if Bale and Hazard are not injured.
In reality, both Bale and Hazard cannot show their best performance anymore. They only have big names but they cannot give significant contributions in the field like previously. Also, you must be aware that both of them are no longer young, they are prone to injury. In my opinion, Real Madrid is better to put these two players on the transfer list and bring Mbappe to Bernabeu.
Yes, Real Madrid does need a striker, not only as a back-up for Benzema but a great player who can play alongside Benzema. In the latest news, Real Madrid has made a £137m offer to PSG to sign Kylian Mbappe. If this offer is rejected, PSG will waste big money because Kylian Mbappe's contract only has a year remaining and it seems that Kylian Mbappe has no intention of extending his contract at PSG.
Real Madrid also desperately needs a center-back and I think Real Madrid should buy a center-back first and then buy a striker. Conceding 3 goals against Levante is proof why Real Madrid really needs a superb center-back.
