Thomas Strunz: Can Luis Diaz match the Bayern Munich success of Franck Ribery?

Bayern Munich hero Thomas Strunz reflects on the Bundesliga champions signing Luis Diaz from Liverpool.
Strunz admits his early impressions are positive, though insists for the money Bayern paid for the Colombia winger, Diaz will need to reach the heights of Franck Ribery.
However, as he says, the early season form of Diaz does suggest he will prove money for value.
