Russell relieved as Mercedes resolve engine issues amid 'toughest psychological' battle

George Russell is optimistic Mercedes have identified and resolved the glitches that have afflicted his car's power unit ahead of this weekend's Hungarian Grand Prix.

Russell slipped 50 points behind title-leading team-mate Kimi Antonelli last weekend at Spa-Francorchamps after making a lap-one exit from the race following contact from Ferrari's Lewis Hamilton.
