The 2017–18 season was Brentford's 128th year in existence and fourth consecutive season in the Championship.[1] Along with competing in the Championship, the club also participated in the FA Cup and League Cup.
The season covers the period from 1 July 2017 to 30 June 2018.
Brentford's first Championship game of the season was at newly promoted Sheffield United which ended in a 1–0 defeat. Billy Sharp headed in a Leon Clarke cross just before half-time. Despite improving in the second-half, Brentford could not find the equaliser.[24] Brentford now have not won on the opening day for six consecutive seasons.[25] On 7 August, young full-back Tom Field joined Bradford City on loan until January.[26] Watkins and Justin Shaibu scored their first goals for the club in the first round of the League Cup against AFC Wimbledon. Their goals came in extra-time after Paul Robinson's first-half lobbed strike and Romaine Sawyers' equaliser in the second-half. The 3–1 result after extra-time sealed Brentford's place in the second round.[27] On 10 August, Cole joined Newport County on loan until January.[28] The B-team midfielder was in the matchday squad for the League Cup tie against AFC Wimbledon. Brentford's first league match at home was a 7-goal thriller against Nottingham Forest. After John Egan's header, two stunning strikes from Andreas Bouchalakis and Daryl Murphy's tap in left the Bees trailing 3–1 midway through the second-half. Andreas Bjelland gave some hope for Brentford as his header was adjudged to have crossed the line by goal-line technology, a first for Griffin Park.[29] However, Kieran Dowell scored for Forest four minutes later and Maupay's late goal proved only to be a consolation with the final score finishing 4–3 to the visitors.[30]
On 15 August, Brentford proposed amendments for the new Brentford Community Stadium which included a decrease in capacity from 20,000 to 17,250 and construction starting in 2018 with completion in late 2019 or early 2020.[31] Midfielder Ryan Woods was given compassionate leave after the tragic loss of his baby.[32] He would not feature for Brentford's next few games. Brentford next faced Bristol City at Griffin Park. Despite conceding an early Josh Brownhill goal, Brentford rallied in the second half and took the lead through Watkins and Maupay and would have been further in front had it not been for an inspired performance from opposing goalkeeper Frank Fielding. Eight minutes into added time due to an injury to Josh McEachran, Bobby Reid pounced and denied Brentford's first league win of the season.[33] The Bees' poor run of results continued at Ipswich Town where, despite a dominant first half, Martyn Waghorn and Joe Garner's goals sealed a 2–0 win for the home side, leaving Brentford bottom of the league table.[34] In the second round of the League Cup, Brentford beat local rivals Queens Park Rangers 4–1 in a West London derby. There were goals from Egan, Maupay and an own goal from Ariel Borysiuk in the first-half, plus one for QPR from Darnell Furlong. Clarke capped off a fine win at Loftus Road with a finish into the bottom corner late in the second-half.[35] Brentford's final game of August ended in a goalless draw against high-spending Wolverhampton Wanderers.[36] Brentford headed into the international break with no wins in their first five league games.
Brentford had a busy final few days of the transfer window. On 30 August, former captain Harlee Dean joined Birmingham City for an undisclosed fee.[37] The following day, on transfer deadline day, Jota and Maxime Colin joined Dean at Birmingham City for undisclosed fees as well, although Jota's fee was confirmed to be Birmingham's record transfer fee.[38][39][40] B-team defenders Jan Holldack and Manny Onariase both left the club for KFC Uerdingen 05 and Rotherham United respectively.[41][42]
September
On 1 September, B-team captain Zain Westbrooke joined Solihull Moors on loan for a month.[43] Brentford's first match after the transfer window was against Aston Villa. Despite a good performance, they could not find a goal to give them their first league victory as the match ended 0–0.[44] On 12 September, Brentford travelled to Hillsborough where they let a lead slip to give Sheffield Wednesday a win. Yennaris scored early with a volley but Gary Hooper netted on the brink of half-time and Ross Wallace completed the comeback from Jordan Rhodes' pull-back. There was concern late into stoppage time as defender Dalsgaard was knocked unconscious and given treatment on the pitch for several minutes before being taken off on a stretcher.[45] Brentford continued their win-less streak in the league at home to Reading. Clarke rifled in from a tight angle after good play between himself and Maupay but Liam Kelly equalised with a penalty after Rico Henry fouled Tyler Blackett as the game ended 1–1.[46] On 18 September, central defender Chris Mepham signed a five-year contract and was promoted to the first team squad.[47] The next day, he made his first competitive start, along with Theo Archibald, in the third round of the League Cup against Norwich City where he gave away the penalty for Norwich's first goal. After Marco Vrancic scored from the spot, Brentford were awarded a penalty themselves, but Yoann Barbet skied it into the stands. Vrancic then curled in a free kick in the second half and Josh Murphy chipped over the oncoming Daniels to give the Canaries a three-goal advantage. Clarke scored a consolation late on as Brentford crashed out of the League Cup, losing 3–1.[48] Brentford finally found their first league win of the season against bottom side Bolton Wanderers. Barbet made amends for his penalty miss in the cup with a superb free-kick in the first half. Yennaris then scored from 30 yards in the second half with Watkins adding a third shortly before full-time.[49] On 26 September, Brentford hosted Derby County at Griffin Park. Despite completely dominating, Brentford could not break down the Derby defence and found themselves behind to Joe Ledley's debut goal for the Rams. It took 86 minutes for Watkins to find a deserved equaliser to grab a point for the Bees.[50] Brentford picked up their sixth draw of the season against Middlesbrough. Despite scoring two goals, courtesy of Barbet's header and Watkins' finish, Middlesbrough came back from behind twice through Martin Braithwaite and Fabio to secure a 2–2 result.[51] Henry was stretchered off in this game and suffered a serious knee injury which would sideline him for a significant length of time.[52]
