Swansea currently sit in second place after winning four of their last five Championship fixtures, while Brentford are unbeaten in 16 matches in the second tier.
However, Cooper has continued to work wonders at the Liberty Stadium, following 13 points from five games in the Championship with a 5-1 victory over Nottingham Forest in the FA Cup fifth round.
Promotion remains a priority for a club who will be braced for competition from several teams below them, including the next visitors to their South Wales home.
Nevertheless, Cooper would have taken satisfaction from how some of his squad players impressed against Forest, aided by Aston Villa loanee Conor Hourihane.
Everything is heading in the right direction for Swansea at this stage of the season, although Cooper knows that things could quickly change if they under-perform in their next match.
While Thomas Frank will be disappointed with cup defeats against Tottenham Hotspur and Leicester City, the Brentford boss will be happy to focus his attention on league matters.
After an indifferent start to the campaign, the Bees have recovered to put themselves on the brink of moving into the automatic promotion places with a game in hand.
Frank will be the first to admit that it will count for nothing if they lose out on Wednesday night, but the opportunity should provide extra motivation to a group of players who have showed few signs of losing in the league since October.
That could soon change when coming up against a team of similar ability and style, although Frank will be optimistic that his players have the character to cope with the increasing expectations which have been placed on their shoulders.
Swansea City Championship form: LWWDWW
Swansea City form (all competitions): WDWWWW
Brentford Championship form: WDWWWW
Brentford form (all competitions): WWLWWL
Frank will be able to call upon Ivan Toney, who missed Brentford's FA Cup defeat to Leicester through suspension.
Swansea City possible starting lineup:
Woodman; Bennett, Cabango, Guehi; Roberts, Grimes, Fulton, Bidwell; Smith; Ayew, Lowe
Brentford possible starting lineup:
Raya; Dalsgaard, Pinnock, Sorensen, Henry; Jensen, Janelt, Ghoddos; Mbuemo, Toney, Canos
We say: Swansea City 1-1 Brentford
In the current climate, Swansea will feel that an extra day of recovery could make all the difference in a game of this magnitude. However, we cannot ignore Brentford's unbeaten streak, and we expect an entertaining encounter to end in a share of the spoils.
