The Heed came into their sixth game of the season unbeaten, whereas the visitors managed to pick up their second win of the season on the weekend.
After a strong Gateshead display in the first half, second half goals from Jimmy Spencer, Luke Parkin and Tyler Walton saw the Celt Army take all three points back to The Citadel and hand the Heed their first defeat of the season.
Player-coach Michael Nelson was disappointed following the 3-0 defeat, telling gateshead-fc.com: “It was poor.
“In the first half we were good and started the game well, we got in some good positions and put some crosses into the box but never really tested the keeper.
“Obviously we hit the crossbar but they had a little chance as well and hit the post; overall in the first half I think we were the better team though.
“In the second half we got what we deserved."
Nelson, who played over 250 games for Hartlepool United, admitted that he felt Jimmy Spencer’s opening goal changed the game: “Goals change games and the first goal is massive in so many ways.
“I think you could see as soon as they scored, we went into pieces a little bit and never really recovered."
The loss also ends a five game unbeaten run for the Heed, during which the 39-year-old played in two games.
The Heed now head to table-toppers York City on Bank Holiday Monday as they look to put things right.
“We’ve had a few draws and managed to get our first win last week and we were looking to bounce on from that this weekend," Nelson added.
"We’ll watch the game back and work on things moving into Monday.
“It’ll also be a chance for some of the lads to put things right [at York] and try to have an impact."
