Callum Wilson scored just six minutes into his full debut and captain Nathan Collins converted two headers as Brentford routed Championship side Birmingham 6-1.

The 34-year-old Wilson, who joined on a free transfer from relegated West Ham, seized his first opportunity with a crisp finish which took a deflection off defender Dael Fry, who had a debut to forget.

Brentford’s Premier League quality was evident throughout and although Blues equalised through Demarai Gray just before the half-hour they were level for just seven minutes.

Lax defending saw Aaron Hickey and Republic of Ireland centre-back Collins score in quick succession to effectively seal the tie before half-time, with Mikkel Damsgaard getting on the end of a counter-attack to add the fourth.

Igor Thiago’s smart close-range finish sent fans streaming for the exit, missing Collins’ second header.

However, the gulf to a Premier League squad was evident as Keith Andrews retained only three of the team which demolished Tottenham and saw three of his newcomers score and another, Yehor Yarmoliuk, run the midfield before he was forced off with injury.

Davies wants to meet the club’s aspirations by playing their way out of the Championship but it proved their undoing before they had even had chance to get a foothold in the game as they fell foul of Brentford’s high press at a short goal-kick.

Paik Seung-ho was slow to react to the loose ball and Yarmoliuk played in Wilson to fire home first-time from the edge of the area with the aid of a deflection.

But a miscontrol by Jannik Schuster saw the centre-back booked for bringing down Luis Vazquez and from Paik’s short free-kick Gray drilled a deflected shot through a crowd of players.

It was a brief moment of joy in an otherwise chastening night as a failure to deal with Vitaly Janelt’s chip and Wilson’s strength allowed Hickey to fire home an angled shot.

Collins jumped in front of Fry to nod in a simple header from Jaidon Anthony’s cross but a ruthless Brentford went for the kill and, after bringing on the likes of Igor Thiago, Kevin Schade and Mamadou Sangare, scored three more after the break.

Meanwhile, Leeds produced a second win at Nottingham Forest in three days as they booked their spot in the third round.

Daniel Farke’s side took the three Premier League points home on Saturday and earned a 2-0 victory in the League Cup thanks to goals from Dan James and James Justin.

Having not won at the City Ground since 1972 before the weekend, they have now triumphed there twice in 72 hours as the Yorkshire club enjoy a winning start to the new campaign.

Teenager Josh Ayala scored twice on his full professional debut as West Ham came from behind to thrash Championship rivals Southampton 4-1.

Elsewhere, Marcelino Nunez scored a sensational goal from the halfway line to help Ipswich claim a hard-fought 3-1 win over Leicester, while ex-League of Ireland stars Mason Melia and Josh Honohan featured as Lincoln progressed after a 4-1 victory over 10-man Blackpool at Bloomfield Road.
