Chris Wilder expects an 'exciting' game against Dean Smith's Brentford on Good Friday.
Speaking about the Bees and the challenge they will pose, Wilder acknowledges they are a side that have the potential to cause his side problems in the capital.
Looking ahead, the United chief remarked: "Technically Brentford are an excellent side and we enjoyed the better of a great game against them on the opening day of the season.
"They are a really good side on their day and that game could have gone either way.
"Brentford are consistently a very good side and were unfortunate not to get anything from games against Cardiff and Middlesbrough."
Wilder added: "They are capable of beating the best teams, like we can, but they can also be beaten.
"They move the ball round the pitch, they are athletic and have a lot of pace and ability in the team too.
"This will an exciting game, both teams will be going all out to win and looking at Brentford need to go and win two games over Easter to get into play-off contention."
