James Ward-Prowse, a man of the moment, sees no reason why he can not cause a discomfort against Manchester United in shape tomorrow.
Ralph Hasenhuttl's team jumped over Cardiff to exit the relegation zone when they beat Fulham 2-0 on Wednesday night.
And Ward-Prowse, who won Saints's second goal in that victory, is ready to give that positivity to Old Trafford.
The 24-year-old said: "It will be tough, they are going great, they have not lost in the Premier League under their new manager, so it will be tough, but it's a special place to go.
"You always want to play Old Trafford to try and provoke an upset.
"We've already done a couple of times before, so why not do it this time?
"His [Old Trafford] a great place to stay. It is full of history. It will be important to focus on our game plan now, but we need to recover properly and make sure we are ready to go.
"We can not wait to do a difficult test."
The saints can go to the Theater of Dreams knowing that they had the better of Manchester United in turn in a not too distant past.
They recorded two away wins for 1-0 in their respective seasons [2014/15, 2015/16].
Ward-Prowse played in both games, so he knows what it takes to beat the giants of English football.
He added: "I think you have to be defensively very good and solid.
"You have to have some luck on your way and you have to be clinician when the odds come to you.
"We have some good memories there, we scored some good goals there and we need to take that positivity in the game."
Saints' chances of a surprise victory could be increased by the number of absences in the Manchester United line-up on Wednesday evening.
Ole Gunnar Solskjaer was without 10 of his players for the game against Crystal Palace – although this did not stop them from winning 3-1, which is why Ward-Prowse is not reading too much about their injury problems.
"With a team like that, there will always be quality players to come and fill the void," he continued.
"We will have to make sure that, whoever emits, we agree with them and win the battle, I can focus only on my game and implement what I know I can do and hopefully we can get a good performance."
