Wayne Routledge, Andy Carroll, Peter Lovenkrands and Ryan Taylor scored the goals for the Magpies.
“It is what we have come to expect, we came up against a Coventry side in good form that worked very, very hard,” he said.
“When they got the goal, which was possibly against the run of play, it spurred us on and I think that fact we got the goal back relatively early helped.
“The formations we have played here at home in the last couple of games have been more offensive and you hope when you do that you can capitalise.
“The standards we have set ourselves this season mean we will have our highs and lows and the last two away games, especially Derby, have not shown us at our best.
“When you are not at your best you hope you can nick something, which we were able to do at Swansea.
“We will certainly need to take some of our home form into our away form to achieve what we want to achieve this season.”
