Diego Costa certainly helped Chelsea this season with his 20 league goals, but how important are 20-goal-a-season players for Premier League success?
Well, if your aim is just to get into the Champions League then such players are not particularly important.
Only 46 per cent (26) of Premier League sides to finish in the top four since 2001-02, when four Champions League places were awarded to England, have had a player who scored 20 or more league goals during the campaign.
On average, the top scorer of the side finishing in fourth scores 16.6 league goals in the season.
The top scorer of the side finishing in third averages 17.6 goals, the one in second 20.4 and the one in first 22.3.
In fact, sides finishing in fourth have had top scorers with as little as 11 goals to their name at the end of the season - Tim Cahill for Everton in 2004-05 and Robin van Persie for Arsenal in both 2006-07 and 2008-09.
If your team is wanting to win the league though a 20-goal-a-season man is a bit more important - but not as much as you might think.
Just over half of all the Premier League champions since the start of the competition in 1992-93 have had a 20-goal-a-season player, 52%.
Only 12 of the 23 Premier League seasons have had champions whose top scorer bagged 20 or more goals, leaving 11 campaigns where the winners' top marksman bagged 19 or fewer goals.

As long as you have a player who can score 13 goals, then you're in with a shout of the title it seems.
In the 2004-05 season Chelsea's top scorer, Frank Lampard, had just 13 goals, but Jose Mourinho's side still won the league.
Thierry Henry was top scorer that year on 25, while relegated Crystal Palace's Andy Johnson had 21 goals to his name.
In 1995-96 Manchester United were crowned champions but Eric Cantona, their top scorer that year, had just 14 goals to his name.
Sir Alex Ferguson's side won the inaugural Premier League in 1992-93 with Mark Hughes as top scorer on 15, while in 2000-01 they won the league with Teddy Sheringham as top scorer on 15.
Arsenal won the league in 1997-98 with Dennis Bergkamp as their top scorer on 16 goals, and Manchester United managed it again in 2006-07 with Cristiano Ronaldo as top scorer on 17.
However, you have to go back seven seasons to 2008-09 for the last time that a team won the league without a player who scored 20 or more league goals in the campaign.
That was once again Manchester United's year, Ronaldo the top scorer on 18.
Since then every side has had a player to have scored 20 or more league goals.
