Agree with you on Jones. Can't really see Grigg accepting a call-up to be honest. From my understanding, he's reluctant to commit to us given his non-existent game time at the euros, citing "family reasons" as his excuse to remain absent.
This game has the potential to be the start of a new era for us. With MON signing a new contract, the EURO 2020 qualifying campaign approaching us and the inevitable additions of new faces such as Lewis, Peacock-Farrell, Kee and Smyth, things look bright. The likes of Jones and Saville also have the chance to make a name for themselves against South Korea, nailing down starting places for the campaign ahead. South Korea are a quality opposition, however.
I'll make a bold prediction of 2-0 to OWC, with goals coming from Washington and Saville.
