It's been a tough season for Daniel Sturridge at Liverpool.

Far from ripping apart Premier League defences in tandem with Luis Suarez on a weekly basis in 2013/14, the England international has managed just six goals across all competitions, four of which came in the EFL Cup against Championship outfit Burton and a severely weakened Spurs side.

The 27-year-old was in EFL Cup action once again at Anfield on Wednesday night, but two fantastic chances passed him by as Southampton marched onwards to Wembley with an impressive 2-0 aggregate win - a real masterclass in counter-attacking football.

Needless to say, Sturridge has had up plenty of stick since the final whistle, with Liverpool legend Jamie Carragher even claiming it's like the Reds are playing with ten men when he's on the pitch sometimes.

Undoubtedly, Sturridge is a shadow of the striker we saw at Anfield a few years ago - and here are THREE key statistics that sum up his ongoing Liverpool plight.

Performance against Southampton

Sturridge was by no means the only culprit as Liverpool were dumped out of the EFL Cup but nonetheless, the performance epitomised how he's struggled this season.

Throughout the 90 minutes, in addition to passing up two glorious opportunities to score, the England forward managed just one shot on target, two successful dribbles and one created chance. Perhaps most worryingly, he finished up with the fewest touches and fewest passes of any Reds player.

A tough evening amid a very tough season for the former Manchester City and Chelsea starlet.

Sturridge vs. the best in the Prem

To give credit where it's due, Carragher's claims don't quite stand up against the statistics.

Indeed, when compared on per-90-minute metrics rather than per-appearance, Sturridge's all-round contribution is pretty much in line with the Premier League's top performing forwards this season, namely Diego Costa, Harry Kane, Zlatan Ibrahimovic and Alexis Sanchez. In fact, he ranks first in terms of shots and duels won and second for successful dribbles - only bettered by the Arsenal talisman, who's had the benefit of room out wide for significant portions of the campaign.

Inevitably, however, it's hard to overlook Sturridge's modest return of goals and assists.

Life under Klopp

That being said, it's quite clear Sturridge just doesn't fit into this Liverpool team under Klopp.

His strike-rate has dropped from better than one-in-two and his win rate has slumped by a very significant 10%. Of course, injuries have been a factor and some argue the England international simply isn't the player he once was, but these statistics suggest a more accommodating manager, such as Brendan Rodgers, could quickly bring out the best in Sturridge once again. Time to move on?
