Although Swansea remain bottom of the league with 16 games left to play, there has been an air of optimism since Carvalhal arrived to succeed Paul Clement.
"To win a game like this you have to be organised, first of all, and your attitude and commitment must be strong", Carvalhal said.
Indeed, the Magpies boss believes that the ex-Stoke star is proving himself to be a snip at just £5m.
'We can not sell players that are playing because we would have to replace them for better players and, in January, we would need a lot of money to convince players to come here, that is nearly impossible in January, ' said Benitez. Managing to score just 13 goals in their 22 Premier League matches, no side in England's top flight has scored fewer goals than the Swans. But maybe we would have to pay £25million or something like that.
It isn't the first time the England global has reacted badly to being hauled off and, in a separate Chronicle article, Benitez reflected on the issue surrounding his and Shelvey's apparent disagreement.
"When you are not winning a game like this one, so important, any player has to be disappointed if they do not continue playing", he said.
"But we have to make the substitutions and that is it".
"I didn't have any problem".
After a goalless first half, Ayew's header in the 60th minute opened the scoring at the St. James' Park - his third goal in last five top-flight appearances. "It is the opposite, a chance for us to enjoy and fight for the three points".
"I think it's quite positive to see players pushing and working so hard when they come from the bench".
Newcastle pressed for a victor without creating many chances to find to it, and Swansea would have stolen the points had Wilfried Bony not seen a goal-bound effort cleared with Darlow stranded, the draw making it just one defeat in four in all competitions for Carvalhal, a run that will provide little solace for the Portuguese given the team's predicament.
