Fabio Carvalho and Igor Thiago scored against the run of play as Brentford frustrated Bournemouth in the second round of the EFL Cup.
Both sides had gone close mid-way through the first half after a dull opening – Carvalho brushed the outside of the post after pouncing on a turnover, before Cherries captain Ryan Christie hit the woodwork with a deflected 25-yard strike.
Bournemouth enjoyed almost 65% possession in the first half, but a defensive lapse allowed their Premier League opponents to break the deadlock.
Defender Kristoffer Ajer met a diagonal free-kick with a header back across the penalty area, which Carvalho met unmarked to side foot past Djordje Petrovic in the Bournemouth goal.
The home side continued to probe after the break, but were caught cold by a swift Brentford transition when Alex Scott – who was Bournemouth’s creator in chief – lost possession inside his own half.
Frank Onyeka led the charge into the penalty area, before squaring across goal for Igor Thiago to score his second goal of the season.
Andoni Iraola threw on forwards Antoine Semenyo and Evanilson, and the pair would have combined to reduce the deficit had the excellent Ajer not cleared off the goal-line with goalkeeper Hakon Valdimarsson beaten.
The Icelandic international again denied Evanilson as full-time approached, summing up a frustrating evening for the hosts.
The host’s frustrations were compounded when defender Julian Araujo was sent off, receiving a second yellow card for a late studs-up challenge on Thiago.
Bournemouth have now failed to win any of their last eight games against Brentford, losing six and drawing twice and conceding two or more goals in seven of those meetings.
