Benteke made a big difference when he came on today.
I disagree with you Khaled Modern day football does have room for an old fashioned no. 9 in the mould of Benteke, Lukaku, Drogba etc. Especially for certain systems and tactics or formations. In a 4-2-3-1 an old fashioned No.9 is quite vital I'd have thought. Drogba is the prime example of this.
Modern football isn't about one system or tactic. Of course everything evolves but in football there will always be room for an old fashioned No.9 for teams who play a certain way. Of course for a team like Barca they'll never employ such a tactic but the likes of Real or Bayern or Utd could do and have done in the past.
In regards to Benteke I hope he can stay fit because he is definitely suited to a Klopp team.
