My goals have been crucial – Costa knows his value to Chelsea

Diego Costa said his goals have been pivotal in
Chelsea's push for a domestic double in Antonio
Conte's first season at the helm.
The Spain striker has netted 19 times in 32
Premier League outings this term and his double
against Southampton last month saw him
surpass 50 top-flight strikes for the Blues.
Chelsea – who secured an FA Cup final spot by
beating Tottenham 4-2 in April – will move seven
points clear at the summit with a win over
Middlesbrough on Monday and Costa knows how
valuable his contribution has been as he eyes the
20-goal mark.
"Twenty is a good, solid total. Any club with a
striker who is going to get 20 goals regularly, they
are going to be up there competing for whatever
competition they are involved in," the 28-year-old
told Chelsea's official website.
"I am not one who is going to be looking at the
goalscoring chart and I am not one who is looking
for individual glory, it is always about scoring goals
to pick up points.
"That is why I am looking for that consistency, that
regularity of scoring, one goal every game or every
other game rather than getting three or four and
then having a drought.
"But with 20 I am happy. I did it in the first season
at Chelsea, when we were champions, and if I get
19 or 20 this season and we turn out to be
champions then great, it means something and it is
for something."
Costa has been linked with a mega-money move
to Tianjin Quanjian, although the Chinese Super
League club released a statement this week
insisting they had "not been communicating with
Diego Costa regarding the transfer".
