Plymouth Argyle head coach Wayne Rooney told BBC Radio Devon:
"I'm disappointed, angry, surprised.
"I think from everything we've seen from the players throughout pre-season today was a surprise to me.
"We knew it was important to try and get through the first 20 minutes and then try and get some composure and some calmness to the game, and we didn't manage to do that.
"I think the basics of the game today was not good enough and for me that's not acceptable.
"Whether that's getting to the ball, tackling, being aggressive and staying with runners - we knew Sheffield Wednesday were one of the best teams in the league last season at crosses and cutbacks and it was four goals from crosses and cutbacks, which we worked a lot on throughout the week, so I'm really disappointed."
Sheffield Wednesday head coach Danny Rohl told BBC Radio Sheffield:
"For me the big outcome from the last six weeks was to see we are fit, we can run, we played good football with the ball and were very strong against the ball.
"It was an outstanding performance, but I think this is just the first step - after six weeks you never know where you are really.
"We spoke a lot during the week about how we defend, it was a big topic with the ball, but our basics are always against the ball and [to] be ready to defend as a team, to attack as a team, and it was good to see.
"We showed a lot of right things, but not more. Everybody can smile today, we can enjoy it, but tomorrow we start again."
