Steve McClaren insists he will play his “strongest team possible” against Northampton in the Capital One Cup tomorrow night.
The League Two side head to St James’s Park for the second round clash.
And while McClaren is expected to make several changes, he insists the club is taking it seriously and he has a squad big enough and with enough quality.
Vurnon Anita will be rested after he took a knock to his back at Old Trafford, while Fabricio Coloccini will also be rested.
The likes of Mike Williamson, Florian Thauvin, Cheik Tiote and Siem de Jong are expected to start the match.
Asked whether it was a priority, McClaren said: “Very serious. It can be a great boost for you.
“It’s another game and nobody – nobody – in football wants to lose a football match and they put a team out that can win that game, and that’s what we will be doing tomorrow.
“We’ll be putting our strongest team possible out, taking into account what happened on Saturday, taking into account there’s a game next Saturday, taking into account that we have got a very good squad.
“But tomorrow night’s team is strong enough and good enough to win the game.
“The attitude has to be right, though,” added McClaren at his pre-match press conference.
Newcastle host League Two Northampton and McClaren says his side can expect a tough evening.
He added: “They’re a good team.
“We have been watching them and they are physically strong, lots of crosses.
“Any team that plays football – and I know from cup competitions - any team on their day can beat anybody no matter what division and if we are not right and we don’t do it right.”
With the summer transfer window closing a week tomorrow, McClaren insists he is happy with the business done so far.
He added “I’m just expecting a busy week because we have got three games in the week.
“I’m sure if things happen, things happen and we will be ready to deal with that and any opportunities.
“But at the present moment, as I said on Friday, we are happy with what we have got.
“Let’s keep our heads down and let’s keep quiet.”
