West Ham United's last European semi-final offered up a result to savour for those in Claret and Blue: the Hammers overturned a 2-1 away first-leg deficit to make it through to the Cup Winners’ Cup final at the expense of Eintracht Frankfurt back in Spring 1976.
Now, on the eve of our first continental semi-final since that occasion, we're challenging you to name all eleven players who started both legs against Frankfurt - also this season's UEFA Europa League semi-final opponents - in our quiz below.
See if you can name them all in three minutes - good luck!
