Brentford v Leyton Orient
npower League 1
Griffin Park, Tuesday January 22, 7.45pm
ORIENT travel to Brentford on Tuesday night looking to complete a London derby double, having defeated the Bees 1-0 at Brisbane Road earlier in the season.
Here, leytonorient.com brings you all the essential pre-match info.
BACKGROUND: Uwe Rösler's Brentford side have established themselves as one of the leading candidates for promotion from League 1 with a stunning run of form in recent weeks.
Their 2-1 defeat at home to table-topping Tranmere Rovers was their first in 14 League matches - a run which has seen them rise up to fourth in the table, seven points off the top two with a game in hand.
The unbeaten sequence included impressive victories over Sheffield United, Milton Keynes Dons and Notts County as the Bees steadily climbed towards the top of League 1.
Orient, meanwhile, will be looking to bounce back from a 2-0 defeat suffered at Doncaster Rovers on Saturday.
The O's were still clearly feeling the effects of their FA Cup exertions against Hull City, but it won't get any easier against the high-flying Bees.
THE HISTORY: Orient will be attempting to complete their first ever double over Brentford this evening, after Ryan Brunt's goal gave Russell Slade's men the points in E10 in September.
In recent years, the pattern has seen Orient claim maximum points at home, while the Bees have tended to return the favour at Griffin Park.
Last season, they thumped Orient 5-0 in west London, but the O's claimed some revenge by triumphing 2-0 in the return fixture.
It total, the teams have met on 46 occasions, with 14 wins for the O's and 21 to Brentford.
TEAM NEWS: Orient will again give late fitness tests to a number of players ahead of Tuesday's game.
Mathieu Baudry, Kevin Lisbie and Nathan Clarke were among the absentees at Doncaster at the weekend, while debutant Ade Azeez was forced off at half time with a sore hamstring.
Russell Slade has added Elliot Omozusi to his squad however, and he is available for selection for this evening's game.
Brentford, meanwhile, are without long-term absentees Kevin O'Connor (ankle) and Farid El Alagui (knee).
