Brentford boss Mark Warburton played down the importance of his side's top-of-the-table clash at Leyton Orient after another comfortable home win.

The Bees were dominant in a one-sided second half as they strolled to a 2-0 success over strugglers Tranmere Rovers ahead of their London derby on Saturday.

Goals from James Tarkowski and Clayton Donaldson were enough to keep the Bees breathing down the neck of the top two.

But Warburton insisted: "Saturday's game is just another three points.

"We will go there and be the best we can be and if we are the best we can be we will be okay."

But Tranmere had the better chances in the first half, Ryan Lowe's rising drive bouncing to safety off the top of the bar and Stephen Arthurworrey finding the woodwork with a header from Jason Koumas' corner.

They were made to pay when Bees centre-back Tarkowski broke the deadlock on the hour, rising highest at the far post to head Jake Bidwell's whipped free-kick past Owain Fon Williams.

But Brentford always looked the more likely to find the net, with Donaldson twice heading narrowly wide and finding the upright with an angled drive while Marcello Trotta tested the side netting with a low drive.

Warburton said: "It is a tribute to us that sides are coming here and parking the bus. I don't think too many want to come here and take us on football-wise because we have some good players.

"We were maybe a bit deep and could have been more clinical, but in the end we kept our heads and played our football at our intensity and our tempo."

Warburton has been amazed at the level the top sides have maintained and believes there will be some sides with 90 points who don't go up, but added: "We are right in there and it is in our hands."

Tranmere caretaker boss John McMahon believes Brentford will be in there come May, and added: "I think we competed and were in their faces but they were the better side with better players.

"The two that hit the woodwork were typical of things just not happening for us at the moment, but we can make excuses all day - the bottom line is we were beaten by a better side."

He urged his players to recognise the difference between being composed and casual, blaming the Brentford opener on a lapse in concentration.

"We are just not dealing with some balls into the box which is disappointing, but there were some positives for us to work on."
