GetWestLondon has taken a look at the sides who Brentford could be facing next season.
Scunthorpe United
Last Brentford Meeting: Tom Adeyemi's strike 20 minutes from time gave Brentford a 1-0 victory over a Scunthorpe side who were relegated from League One that season in March 2013.
The Bees had also drawn at Glanford Park earlier that season as Harry Forrester's goal before half time was cancelled out by Leon Clarke.
Brentford's record: Won 16, Drew 12, Lost 11
Distance from Griffin Park: 193 miles.
Other information: Iron forward Paddy Madden scored in Yeovil's 2-1 triumph over Brentford in the 2013 play-off final.
Fleetwood Town
Last Brentford Meeting: Brentford have never faced Fleetwood in any competition before in their history.
Distance from Griffin Park: 248 miles.
Other information: Former Bees boss Uwe Rosler is now in charge of the Cod Army. The German spent two and a half seasons in charge at Griffin Park, taking them to the League One play-off final in 2013 before leaving for Wigan in December that year.
Bradford City
Last Brentford Meeting: Clayton Donaldson and George Saville struck second half goals as the Bees took a step towards promotion from League One in March 2014.

The Lions, who were relegated from the Championship that season, had taken a 2-0 lead thanks to goals from Lee Gregory and Aiden O'Brien. However, Alex Pritchard's penalty and a Moses Odubajo equaliser saw the Bees claim a share of the spoils.
Brentford claimed victory at The Den earlier that season in a ding dong tussle against a Millwall side wearing a special camouflage kit to raise money for Headley Court.
Andre Gray had given the Bees a two-goal lead before Lee Gregory and Alan Dunne scored twice in two minutes to make it 2-2. A Danny Shittu own goal gave Brentford all three points.
Brentford's record: Won 22, Drew 21, Lost 20
