Jonny is expected to play at left wing-back in a 3-4-3 formation following the departure of Barry Douglas to Leeds United.
He scored twice and provided one assist in 36 appearances for Celta Vigo in 2017/18.
The 24-year-old also had 15 shots and created 22 chances in LaLiga.
But it is his defensive work that can make the greatest impact for Wolves.
His 79 successful tackles last season were more than any FPL defender.
And his 93 interceptions were higher than anyone in the Premier League regardless of position.
Those contributions can help him claim additional points in the Bonus Points System (BPS).
So whenever Wolves supply a clean sheet, Jonny’s chances of earning bonus points will improve.

Wolves had a fine defensive record on their way to promotion as Championship title-winners.
Their 24 clean sheets and 39 goals conceded were league-leading figures.
And a good opening run of opponents gives them the chance to replicate that form.
Only two of their first 10 matches score more than three in the Fixture Difficulty Ranking (FDR).
This suggests that investment in their team can reward early investors.
But Jonny may need to improve his attacking potential to become their go-to defender.
With four goals and four assists last season, right wing-back Matt Doherty (£4.5m) makes a strong case to be considered their best all-round prospect.
