Montoya won a brave battle of wills with title front-runner Alonso at the British Grand Prix at Silverstone 11 days ago as he duelled with the Spaniard in the first few corners before the Renault driver eventually gave way.
Such an incident appeared to indicate Montoya is back in form after the early part of his season was wrecked by a shoulder injury.
