The Magpies will qualify for the UEFA Europa Conference League if Manchester City beats cross-city rival Manchester United in the FA Cup final next weekend.

After a positive start from Brentford, the visitors took the lead on 21 minutes through Harvey Barnes's header, and their advantage was soon doubled through Jacob Murphy.

Alexander Isak slotted beyond the goalkeeper to make it 3-0 before half-time, but the hosts responded after the interval thanks to goals from Vitaly Janelt and Yoane Wissa.

Bruno Guimaraes got Newcastle's fourth in the 78th minute to ensure the Geordies claimed the three points as they end the season in seventh place, whilst Brentford finished in 16th.

The Bees thought they had made the perfect start inside two minutes but after a VAR check Ivan Toney’s effort was ruled out by referee Simon Hooper for offside.

Toney continued to search for a goal against his former club but was denied by the outstretched leg of Nick Pope.

It was Newcastle that should have taken the lead before the 10-minute mark as Isak set up an unmarked Joelinton from close range, but the Brazilian failed to convert.

The visitors then broke the deadlock on 21 minutes, with Barnes darting into the six-yard box to meet a delightful delivery by Guimaraes and head the visitors ahead.

Sean Longstaff thought he had quickly doubled their advantage, only to be flagged offside, but Murphy was not denied when he latched onto Isak's exquisite pass across the penalty area to make it 2-0.

Just two minutes later, Isak grabbed his 21st goal of the season when he fired past Mark Flekken.

The Brentford stopper ensured Isak did not extend Newcastle's advantage further with a smart stop to deny the Sweden international before half-time.

The home side responded after the interval and Janelt reduced the deficit, striking home after being picked out by Wissa.

Pope clawed away Toney’s header before Wissa curled a superb effort past the goalkeeper to set up a tense finale for the visitors.

The nerves, though, were soon settled when Guimaraes followed up a free-kick to ensure the points returned to Tyneside.
