Portsmouth's unlikely 2-0 extra time victory over Tottenham Hotspur at Wembley was arguably an even greater feat for the Israeli who took over in November with the south coast club apparently heading towards the financial rocks.
NEWS:Pompey upset Spurs in semi final
With debts of around 70 million pounds, problems paying the players salaries and the club finally going into administration in February, triggering a nine-point sanction that made relegation a virtual certainty, the odds have been stacked against Grant.
Yet in adversity, with no cash to spend, players suffering serious injuries and all hope apparently gone, Grant has retained a sense of spirit in a squad who could just have easily gone through the motions before jumping ship.
Pompey, whose fans sung their hearts out on Sunday in what most observers felt would be the club's last day in the sun for some time after relegation was confirmed 24 hours earlier, were given no chance against Harry Redknapp's resurgent Tottenham.

Everything that could go wrong for Portsmouth has done in recent months.
Team leader Hermann Hreidarsson, who along with goalkeeper David James is one of the few survivors from the Redknapp's Portsmouth team that won the Cup in 2008, ruptured his Achilles at Spurs recently, ruling him out of the semi-final.
Jamie O'Hara, Portsmouth's most impressive player, could not play as he was on loan from Tottenham, while on the eve of the game Nadir Belhadj was also crocked.
"Right up to the last minute we didn't know who could play," Grant said. "Players were out of position but despite that we played good football, scored two goals. It's more than an honour to be in the final.
