Paul di Resta believes Force India's resurgence has been secured in the wake of a recent multi-million pound investment by Sahara conglomerate, who bought 42.5% stake in the team from team principal Vijay Mallya for �63.5million.

Commenting on the investment ahead of this weekend's Korean Grand Prix, Di Resta said: "What has now happened is a great thing for Force India, to have that investment coming in.

"As Vijay recently said, his team is becoming what he wants it to be now. I'm sure it will continue on an upward slope."
