Marcus Ericsson believes he should get some recognition for Sauber's upturn in performance in 2018.

The Swiss team has enjoyed their most successful season since 2013 with 42 points on the board, just one short of their cumulative total in the last four years.

Much of that has been down to a tie-up with Alfa Romeo which brought the most current Ferrari engine and Charles Leclerc, who has scored 33 of Sauber's points so far this season.

Even so, Ericsson, who has matched his best ever year in F1 with nine points and was very unfortunate last weekend in Brazil having qualified sixth, doesn't think the Monegasque deserves all the plaudits.

“In Melbourne, we followed Williams along with the field,” the Swede was quoted by PlanetF1

“After that, we’ve improved a lot and I’ve got a stake in it, Charles and I worked hard with the team and tried to steer it in the right direction.”

The respective futures of the two drivers is very different with Leclerc going onto Ferrari next year while Ericsson has been dropped and will head to IndyCar.

“I do not want to close the door to the premier class, but now I’m going to America,” Marcus claimed.

"At the end of the season, I want to prove to the team again why they will miss me.

“They [Ericsson's IndyCar team Schmidt Peterson Motorsport] seem to be happy that I’m coming, and I’m looking forward to moving there.

“I have high expectations, and I want to use the feeling of winning there.”
