Predicted line-up sees David Moyes set to make seven changes for Genk depending on West Ham United injury unknowns.
West Ham are in Belgium looking to make it six consecutive wins in all competitions and four from four in the Europa League.
Do that and the Hammers will seal their place as Group H winners and a spot in the last 16 knockout stages.
Indeed a draw might even be enough for West Ham depending on the result between Zagreb and Rapid Wien.
Should West Ham meet Moyes’s target of getting the job done against Genk it effectively gives his squad a European break until March as the last two group games will not matter.
West Ham beat Genk 3-0 in the home tie a couple of weeks back.
But the hosts have scored six goals in each of their last two games leading up to the clash with West Ham.
Johnson has made the right-back spot his own during Vladimir Coufal’s injury absence.
But the academy graduate will drop out of the side in one of seven changes Moyes looks set to make to the team – depending on the injury unknowns the Scot has hinted at in his pre-match press conference.
Predicted line-up: David Moyes to make seven changes for Genk depending on West Ham injury unknowns
The fact Coufal was alongside Moyes in that press conference suggests he will get a chance to continue his comeback from injury by starting in Johnson’s place.
Moyes may elect to give Aaron Cresswell a well deserved rest by switching Johnson to the left but that remains to be seen.
Alphonse Areola will replace Lukasz Fabianski in goal.
Issa Diop and Craig Dawson will replace Kurt Zouma and Angelo Ogbonna in central defence.
Moyes may elect to keep Declan Rice and Tomas Soucek together in midfield as he has done in previous Europa League games.
Given Said Benrahma’s withdrawal just after the hour against Aston Villa, the Algerian could start against Genk with Manuel Lanzini potentially in line to take his place on Sunday against Liverpool.
But we expect Arthur Masuaku to come in on the left with both Benrahma and Lanzini on the bench.
Jarrod Bowen could also start up front instead of Michail Antonio while Andriy Yarmolenko replaces him on the right.
Nikola Vlasic will come in for Pablo Fornals to complete the changes.
Of course all that hinges on the availability of certain players.
Mark Noble and Alex Kral have been rumoured to be pushing for a start but that seems unlikely as Moyes looks to keep the spine strong and get the job done.
Predicted West Ham starting XI to face Genk:
Areola, Coufal, Dawson, Diop, Cresswell/Johnson, Soucek, Rice, Yarmolenko, Masuaku, Vlasic, Bowen.
