Gylfi Sigurdsson's (£7.2m) lack of form has forced Fantasy Premier League managers to seek out replacements.
The Everton playmaker has suffered 190,000+ sales in the last two Gameweeks, having produced only one goal in his previous eight appearances.
But a trip to Cardiff City raises his prospects.
Sigurdsson scored and returned 11 FPL points during his last meeting with the Bluebirds.
As a result, he is one of four Differentials selected by The Scout for Gameweek 28 ahead of the Tuesday 26 February deadline of 18:45 GMT.
The Icelandic international boasts a major goal threat for Everton's trip to the Cardiff City Stadium.
Sigurdsson's total of 64 shots on goal ranks fourth among FPL midfielders.
That points to a return to form against a Bluebirds' defence that conceded five goals at home to Watford last Friday evening.
The Liverpool playmaker looks set to return to the teamsheet at home to Watford in midweek.
Shaqiri could be handed a central support role, with doubts over the fitness of Roberto Firmino (£9.2m).
The Switzerland international has been more reliable in front of his own fans in 2018/19, scoring five of his six goals at home.
Indeed, Shaqiri's average of 104 minutes per home goal is quicker than any team-mate with more than one goal at Anfield this season.
Lukaku has scored in six of his last nine meetings with the Eagles, including a 3-2 win in the corresponding fixture last season.
Roy Hodgson's side have struggled for resilience in recent matches and recorded only one clean sheet in their last six outings.
Hayden has one goal and three assists over the last five Gameweeks, supplying an assist in all three of United's most recent home fixtures.
Indeed, he has created 10 chances in that period, more than any Magpies' team-mate.
