Newcastle have been blighted by injuries and illness this season and their campaign suffered a huge blow this week when their go-to centre forward Callum Wilson was ruled out for eight weeks.
The striker, signed for £20million from Bournemouth last summer, has become a key figure for Steve Bruce's side, notching 10 goals in the Premier League.
The Magpies have netted 25 goals in total so far this campaign, meaning Wilson has, in fact, scored 40 per cent of their goals. That's the largest share in the Premier League this season.
Newcastle are heavily reliant on Wilson to put the ball into the back of the net with the club's other strikers netting just seven top-flight goals between them.
Miguel Almiron has scored four while Joelinton, Andy Carroll and Dwight Gayle all have just one to their names in the 2020-21 campaign. Wilson has proved decisive and his long-term absence is a massive setback for Newcastle, just when they were building some momentum.
They've won two out of their last three, pulling 10 points clear of the relegation zone but without their talisman fears will be growing among the Newcastle faithful that they could be dragged back into a battle to avoid the drop.
Newcastle depend on Wilson but who do the other 19 Premier League teams count on the most?
Dominic Calvert-Lewin, who is having a fine season netting 13 goals in 21 games, has scored 38.2 per cent of Everton's goals this season while at their Merseyside rivals Liverpool's go-to guy is Mohamed Salah.
The Egyptian forward has netted 16 of the Reds' 44 goals this campaign, equating to 36.4 per cent.
The importance of Harry Kane and Son Heung-min to Jose Mourinho and Tottenham has been clear and unsurprisingly the pair have scored the largest share of the north London club's goals with each scoring 13 out of 36 which is 36.1 per cent.
Two other players responsible for more than 30 per cent of their teams' goals are Wilfried Zaha and David McGoldrick.
It's no secret how pivotal Zaha is to Crystal Palace with the Eagles constantly having a fight on their hands to keep their main man. The winger has scored nine goals of Palace's 27 which is 33.3 per cent.
While goals have been in short supply for relegation-threatened Sheffield United this season, there's no doubt who they want taking aim when the opportunity arises. Like Zaha, McGoldrick has scored 33.3 per cent of the Blades' 15 goals this season.
Another player that contributes more than 30 per cent of their team's goals is Leeds' in-form striker Patrick Bamford. The 27-year-old has defied his critics this season by showing he can certainly cut it in the Premier League.
With Pierre-Emerick Aubameyang struggling for form this season his fellow forward Alexandre Lacazette has proven to be where the Gunners' goal input comes from. The Frenchman has scored eight of Arsenal's 27 goals, equating to 29.6 per cent.
Bobby Decordova-Reid has scored 29.4 per cent of Fulham's goals and while Burnley are the league's lowest scorers with just 14, Chris Wood has scored the biggest proportion of those with 28.6 per cent.
It's no surprise that Leicester rely on Jamie Vardy as their main source for goals with the lethal frontman scoring 11 of 39, equating to 28.2 per cent. Former Liverpool defender Jamie Carragher claimed the Foxes' £1m signing of Vardy from non-League Fleetwood in 2012 was the best transfer in football history.
Brighton can bank on Neal Maupay to score with the forward netting 28 per cent of their 25 goals, while Premier League newcomers Ollie Watkins and Matheus Pereira have scored more than a quarter of Aston Villa's and West Brom's goals at 27.8 per cent respectively.
The only other player to have scored more than 25 per cent of their team's goals is Bruno Fernandes at Manchester United. The Red Devils' star midfielder has netted 13 of their 49 goals - 26.5 per cent.
Southampton striker Danny Ings has notched 24.1 per cent of their goals while Tomas Soucek, who has made a significant impression on David Moyes' West Ham side this season, has netted 23.5 per cent of the Hammers' goals, bagging eight out of 34.
There are four clubs less dependent on one individual to slot the ball home. Predictably with all their wealth of attacking talent Manchester City have not relied heavily on one star this campaign.
Pep Guardiola has had to cope with issues in the frontline this season with Sergio Aguero struggling for fitness, leaving the likes of Raheem Sterling, Kevin De Bruyne, Phil Foden and Ilkay Gundogan to shoulder the responsibility.
Midfielder Gundogan, who was named January's Player of the Month on Friday, has scored the largest percentage of their goals at 20.9 per cent.
Wolves' Raul Jimenez, who is yet to return to action after suffering a fractured skull at the end of November and Pedro Neto have both scored eight goals combined of the side's 23.
Chelsea are the top-flight outfit that pin their hopes on one player the least when it comes to sticking the ball away. Timo Werner's dismal form in his debut season in England is well-documented and there has been plenty of rotation since the £200m-plus summer splurge.
Frank Lampard was in the process of reshaping his team after the summer expenditure but was dismissed amid a run of poor results. Now Thomas Tuchel is at the helm and he is working out his best options. Tammy Abraham is their top contributor with 15.8 per cent of their 38 Premier League goals.
