Manchester United's title charge was slowed when they drew 0-0 at a determined Newcastle United on Tuesday and missed the chance to move nine points clear at the top of the Premier League standings.
United, back in action after being sent tumbling out of the FA Cup by rivals Manchester City in the semi-finals on Saturday, could not break down a resolute Newcastle backline.
The home side dominated possession for large parts of the match at St James Park with Peter Lovenkrands squandering their best opening with a header in the first half. The visitors had a late penalty appeal turned down when Hernandez fell under the challenge of Danny Simpson with the Mexico striker being booked.
United now have 70 points from 33 games, seven points above second-placed Arsenal and nine ahead of Chelsea although the London sides both have a game in hand. Arsenal visit fifth-placed Tottenham Hotspur on Wednesday when Chelsea host Birmingham City.
United, who have now won only five of their 17 away games this season, could have taken the lead in under two minutes when Hernandez latched onto a low cross from Rooney, who was back after a two-match ban, but his close-range effort was smothered by keeper Tim Krul.
The result moves Newcastle above Aston Villa to ninth on goal difference with 40 points from 33 games.
Arsenal's french brigade ponders exit
London: Samir Nasri heads a group of five high-profile French players who are considering their futures with Premier League giants Arsenal, French sport daily L'Equipe claimed on Wednesday.
Nasri will reportedly think about leaving if the central playmaking position he covets is not vacated by the departure of Cesc Fabregas this summer.
L'Equipe claims that Inter Milan are tracking Nasri. The paper does not cite any sources for their claims, apart from an unnamed club insider, who is quoted as saying that some of Arsenal's players "are frustrated and have understood that they might have a better chance of winning trophies elsewhere".
Abou Diaby, Bacary Sagna, Gael Clichy and Sebastien Squillaci were the other names which were mentioned.
