The Scout is tipping four low-owned players who could be set for a breakout Double Gameweek 29 in Fantasy Premier League ahead of Saturday's 11:00 GMT deadline.
Managers on the lookout for a cut-price midfielder should consider the Brazilian.
Crucially, the Gunners are one of only two DGW29 sides who also play in the reduced Gameweek 30, visiting Aston Villa.
Martinelli has been a key figure in Mikel Arteta’s team in recent months.
He has started each of the last 11 matches he has been available for, producing four goals and two assists.
The underlying numbers further highlight Martinelli’s potent goal threat.
His 29 shots and 24 shots in the penalty area each place joint-second with Alexandre Lacazette (£8.3m) for Arsenal from Gameweek 14 onwards.
The Colombian has made an immediate impact for Liverpool since arriving in the January transfer window.
Diaz has been preferred to Diogo Jota (£8.3m) in the Reds' front three in each of their last three matches, scoring against Norwich City in Gameweek 26.
His total of 17 shots in his previous four appearances ranks second only to the 21 of Mohamed Salah (£13.2m) for Jurgen Klopp’s side.
After being rested in Liverpool's UEFA Champions League meeting with Inter Milan in midweek, Diaz will be fully refreshed for their DGW29 encounters with Brighton & Hove Albion and Arsenal.
Richarlison has been far more productive at Goodison Park this season.
He has scored three of his four goals and supplied all three of his assists at home in 2021/22.
The forward is also among Everton's leading goal threats since Frank Lampard was appointed manager in Gameweek 24.
His nine shots and two big chances both place in the top two players for the Toffees from that point.
Doherty has started each of the last two Gameweeks against Leeds United and Everton, delivering 18 and 14 points respectively.
He has combined a goal and three assists with two clean sheets, also collecting five bonus points.
Along with Arsenal, Spurs are the only other DGW29 side who also have a match scheduled in Gameweek 30, hosting West Ham United.
