Manager Uwe Rosler is proud of Brentford after his side survived a late Walsall onslaught to claim all three points at the Banks's Stadium.
The only goal of the game came in the 27th minute when Clayton Donaldson deftly headed in a deep cross from the lively Myles Weston.
Donaldson missed a couple of chances in the second half to finish off Walsall, who came back strongly with Ryan Jarvis hitting a post and Richard Lee pulling off fine saves to deny Kevan Hurst and Alex Nicholls.
"In the first half I felt very comfortable as we restricted Walsall to one corner and they hardly had a shot at goal," said Rosler, who will be looking to strengthen his squad when the loan window re-opens next week. "The players stuck to our game plan but I told them we needed a second goal to kill them off. We had three big chances to do that in the second half and the last 10 to 15 minutes was not nice.
"The home crowd lifted Walsall and this is a tough place to come, it is intimidating. Our keeper made one or two very good saves, but for 75 minutes of the match we were the better team.
"Walsall tried everything in the last 15 minutes to get something out of the game but we defended very well and had a bit of lady luck."
