Scoring one goal in any professional league is hard enough, but putting together a run of consecutive games on the score sheet is something else.
There have been plenty of examples of players managing to embark on such streaks, but they almost always come to an end after four or five games. However, there are a special few who manage to keep that run going even longer.
Here are the eight longest scoring streaks ever.
Jimmy Dunne - 12
Irish legend Jimmy Dunne was absurdly prolific for Sheffield United between 1926 and 1934. After costing the Blades £800, Dunne established himself as one of the finest forwards around, averaging nearly one goal per game across his eight years with the club.
During the 1931/32 campaign, Dunne hit over 30 goals for the third consecutive season. He found the back of the net in 12 consecutive games, actually managing to net 18 goals across that spell.
He actually added a fourth consecutive season with over 30 goals, before leaving Sheffield United to join Arsenal.
Robert Lewandowski - 12
He netted a total of 14 goals across 12 consecutive appearances, although he actually served a two-game suspension after the first five matches of that run, but instantly resumed scoring upon his return.
That was the kind of form which prompted Bayern Munich to sign him in 2014, and he's still similarly prolific to this day.
Stan Mortensen - 15
Like Lewandowski, Blackpool legend Stan Mortensen's presence in the record books is also a bit questionable.
During the 1950/51 campaign, Mortensen netted in 15 consecutive First Division appearances, although that run was broken up as he missed two games through injury.
Mortensen also holds the honour of being the first player to score for England at a World Cup, having netted in a 2-0 win over Chile in 1950.
Tor Henning Hamre - 15
Far from a household name, Norwegian forward Tor Henning Hamre spent most of his career in Scandinavia, but it was his spell in Estonia which earned him a place in the history books.
During his time with Flora Tallinn in the 2003 season, Hamre found the back of the net in 15 consecutive Meistriliiga games, in which he netted an incredibly impressive 21 goals.
It wasn't part of his run, but later in that season, Hamre actually netted seven goals in Flora's 17-0 win over Kuressaare. Not bad.
Josef Martinez - 15
Heartbreak for Atlanta United's Josef Martinez, whose run of scoring in 15 consecutive league games came to an end in a recent 3-1 win over San Jose Earthquakes.
He may not have broken the all-time record, but that 15-game run, in which he netted 21 goals, did break the Major League Soccer record, so it's not all bad for Martinez.
The powerful Venezuelan has been a dominant force in MLS, so it wouldn't come as much of surprise to see him put together a similar hot streak in the future.
Teodor Peterek - 16
Very little is known about Polish striker Teodor Peterek, and even less is known about his goalscoring exploits during his career.
However, he did make history during the 1937/38 campaign with Ruch Chorzów, as he is believed to have netted in 16 games in a row, which was a clear record at the time.
The man known as 'Mietlorz' was a dominant force in Polish football, but all of his accomplishments came before things were officially documented, so he often does not get the credit he deserved.
Gerd Muller - 16
Gerd Muller tied Peterek's record during the 1969/70 campaign when he found the back of the net in 16 consecutive appearances.
After scoring in eight in a row, Muller was completely left out of the matchday squad for a 1-0 win against Hannover, but returned the following week and embarked on another eight-game streak. He ended up with 23 goals across that spell.
Muller is widely viewed as one of the greatest strikers of all time, and he held the scoring record for many, many years, until a certain someone came around.
Lionel Messi - 21
Lionel Messi didn't just break Muller's record, he shattered it in one of the greatest single seasons we have ever seen.
Across the 2012/13 season, Messi netted a ridiculous 60 goals for Barcelona, including finding the back of the net in 21 consecutive appearances. He scored 33 goals across those 21 games, although there was a three-game break as he battled a hamstring injury.
He started that run by netting two goals in each of six straight games, which speaks volumes of just how impressive that campaign was for the iconic Argentine.
