The Black Cats winger will be hoping to damage their defence on Saturday, but he also appreciates the threat that they can pose to his team.
Many have been surprised by the start that Sam Allardyce's side have made, as they have climbed into the top-four at this stage of the season, but Johnson feels that they always had the quality at their disposal to achieve this.
Indeed, the 27-year-old thinks that the likes of Stewart Downing and Andy Carroll deserve to be earning international recognition for their form and he backed the latter to join his former teammate in the England squad in the near future.
“[Carroll and Downing] are two very good players," Johnson is quoted as saying by London24. "I obviously know Stewy and he’s having a great season and he’s earned his chance with England."
"And I think it’s only a matter of time before big Andy gets in there because he’s different to anything else we’ve got.”
Carroll missed much of the start of the season with injury, but since his comeback he has impressed with his dominant performances up-front.
With West Ham increasing the service that the provide for their strikers, Carroll is set to shine and he seems to be thriving with the quality of delivery that he is receiving currently.
The target-man centre-forward scored two goals in his last outing against Swansea City and he will be looking to be similarly as effective this weekend.
Sunderland have proven though to beat this season - losing just four times - but the Hammers are one of the division's form sides and they will be determined to collect the three points to strengthen their grip on a top four spot.
