The Scout is selecting four overlooked players who could be set for a breakout Gameweek 28 in Fantasy Premier League.
Castagne has combined one goal and three FPL assists with four clean sheets in his 17 starts this season.
Sheff Utd's problems at both ends of the pitch look hugely encouraging for Castagne.
Away from home, they have scored only six goals and are yet to keep a clean sheet. Both of those records are the worst in the Premier League this term.
The right-back has benefited from a recent injury to team-mate Matty Cash (£5.0m), starting each of Aston Villa’s last four matches.
At a cost of only £4.3m, he offers a cut-price route into Villa's defence for a trip to Newcastle United.
Villa have recorded eight clean sheets on their travels this season, more than any other side.
The underlying numbers in that period further highlight his influence on the Everton attack.
Indeed, Sigurdsson’s six chances created and four shots on target were both team-leading totals.
The Brighton & Hove Albion right-back offers multiple routes to returns at Southampton.
Veltman has combined one goal and four clean sheets with six bonus points across his last eight outings.
The underlying numbers highlight his major goal threat. Veltman’s nine shots and seven shots in the box in the last four Gameweeks both rank top among defenders.
