His goals in the past month have effectively earned the Clarets four points; a vital strike in a 1-1 draw with Southampton; the equaliser in an outstanding 2-1 comeback against Everton; and the opener in a 3-0 victory against West Ham United at the London Stadium.
The 28-year-old's form has led to talk he could receive his first senior cap for Austria, who he represented at under-20 level. There were also reports in January of interest from Chelsea, at the time they were dismissed but perhaps the stories weren't so outlandish after all.
However, how does the Turf Moor frontman compare to other goalscorers at similarly-sized clubs around the Premier League? We've taken a look at the data.
With six goals to his name in the top flight this season, Barnes isn’t hitting the same lofty heights of Brighton and Hove Albion's Glenn Murray’s (11). But he does hold his own against many comparable strikers.
Watford's Troy Deeney, another physical frontman, has netted just five times while Crystal Palace's Christian Benteke, a man who has commanded in excess of £70million in transfer fees during his career, has just two goals to his name this term.
Burnley fans will accept Barnes’ form in front of goal has been erratic this season yet he averages, as the graphic above shows, more scoring attempts per 90 than the other striking trio.
And while Murray and Deeney are outperforming their xG (expected goals) for the campaign, Barnes' is pretty much on par. While that isn't a negative, it shows he is netting chances he is expected to score and little else.
Benteke, however, is having a very poor season in front of goal and is failing to match his xG for the campaign so far by some distance.
At Burnley Sean Dyche doesn't have the luxury of picking from a large pool of goalscorers and in Barnes and Chris Wood they have two strikers that undoubtedly chip in with their fair share.
Tellingly, Barnes is second only to Murray when it comes to the proportion of his club’s league goals scored, with 22 per cent.
So while he isn't as prolific as the Brighton frontman, there is no doubting his importance to his respective side.
And if Barnes keeps his recent form up then he could lead Burnley's charge into Europe.
