Danny Rose harbours aspirations of returning before the end of the season.
The popular midfielder has been injured since breaking his leg against Northampton in December.
And his potential comeback should certainly benefit the Blues if the numbers are taken into consideration.
Indeed, the stats show Kenny Jackett’s side are worse off without Rose in the team.
The 30-year-old has made 15 League One appearances this term.
After having a spell on the periphery of things – missing out on a place in the Blues’ match-day squad on several occasions – Rose returned and played a key role in a Pompey run which saw them reach the League One play-off spots before the turn of the year.
And the former Oxford United talent’s absence seems to be a significant factor behind the Blues’ poor form in 2018.
When Rose has been in the team this season, Jackett’s troops have won 60 per cent of their games.
The Blues were picking up an average of 1.8 points per match.
That sort of form would have almost certainly clinched them a place in the top six come May.
Meanwhile, the Blues were scoring 1.27 goals per league game and conceding just one with the Bristol-born talent in their side.
He also helped his team deliver five clean sheets.
From the 20 league games Rose hasn’t featured in, Pompey have delivered just six wins – a percentage of only 30.
That’s a points-per-game ratio of just 0.9, which is in reality relegation form.
Jackett’s side have also been conceding considerably more at a ratio of 1.45 goals per game.
Moreover, Pompey have recorded just three clean sheets without him – and not one since Rose has been out with his broken leg.
Ben Close and Adam May have both enjoyed breakthrough years and have big futures ahead.
But the numbers show Pompey have clearly missed the experience and nous of Rose in their engine room.
