If Frank Lampard was watching Leicester City's defeat to Roma in the Europa Conference League on Thursday evening, as you expect he might well have been, then he could have been given a stark reminder of an important weakness to exploit.
But, he will know that his Everton side will have to do a lot of work themselves if they are to get to that level by the time they travel to the King Power Stadium on Sunday afternoon.
It took 11 minutes on Thursday for the Foxes to show their Achilles' heel once more. Lorenzo Pellegrini whipping in a good, out-swinging corner into the box where he found Tammy Abraham rising well above anyone else to plant a firm header beyond Kasper Schmeichel - ultimately putting the tie beyond Brendan Rodgers' side in the process.
