Plymouth manager Ian Foster was furious with referee James Linington after his side lost 2-1 at Norwich to stay deep in the Sky Bet Championship relegation scrap.
The high-flying Canaries scored two second-half goals to take the points, after being stunned by Morgan Whittaker’s 10th-minute opener, his 20th of the season.
The second-half comeback brought Linington’s decision not to award a penalty to Plymouth when Alfie Devine went down under a challenge from keeper Angus Gunn under the spotlight, while the official’s insistence that Lewis Gibson went off before the corner that led to the winner was also a bone of contention.
“All we ask is that the officials make the right calls and that wasn’t the case today,” said Foster.
“I thought the referee got lots of decisions wrong and two of them were absolutely key decisions in the game.
“For me it was a clear penalty. Their keeper slid in, didn’t get the ball and took Alfie out – but he gave a yellow card to Alfie.
“For the corner there was a collision between two of our players and immediately the referee calls the physio on – he doesn’t ask if our player needed treatment, which he didn’t, he was fine.
“We have to accept responsibility for not defending set-plays properly – but it was still frustrating.
“I think the loyal fans who travelled all this way to follow their team would have been proud of the performance – I know I am.
“We have spoken about being more ruthless at the key moments in both boxes but overall there were a lot of positives to take from that.”
The match was settled by two goals inside seven minutes, both from right-wing corners.
The first was a set routine, with substitute Christian Fassnacht playing the ball low into the path of the deep lying Josh Sargent, who had the space he needed to sweep home his 14th goal of the season.
Regular taker Gabriel Sara then sent in a more conventional corner to the near past where Sam McCallum headed it on and a deflection off Ashley Phillips took the ball into far corner of the net.
It was a deserved win for Norwich, but relegation-threatened Plymouth gave the hosts a scare by taking the lead after just 10 minutes when Whittaker nodded home Matthew Sorinola’s cross to make it 20 for the season.
“It was a big win for us, especially after going behind so early,” said Norwich head coach David Wagner.
“In the first half I thought we played really well, we didn’t let the goal affect us and created lots of chances without being able to take them.
“In the second half we were not so good and sometimes over the course of the season you have to rely on your set-pieces, which we work on very hard.
“Overall it was probably not at the level we have shown over the past few games but once again the players have put in a shift, shown their togetherness to get the result we wanted.”
