It was inside 50 minutes, Crystal Palace were 2-0 down against Leicester City – down but probably not out – Patrick Vieira’s men pressing and harrying their opponents but without any real incision or cutting edge in the final third. It had been the story of their season so far, conjuring up fine openings but lacking the ruthlessness when it mattered most.

Vieira knew that, and felt it was the perfect time for a change, for a fresh new impetus, and a significant one it turned out to be.

On came new summer signing and exciting young midfielder Michael Olise in place of the misfiring Jordan Ayew.

As soon as the 19-year-old wonderkid took his position on the pitch, Palace instantly stepped it up a notch and the former Reading man was at the centre of it alongside fellow substitute and goalscorer Jeffrey Schlupp, Odsonne Edouard and Wilfried Zaha.

Every time Olise took possession, he attempted to make things happen, expressing his bravery and courage on the ball, taking on Premier League experienced full-back Ryan Bertrand at every opportunity.

There was a moment soon after Olise came on, picking up the ball with his back to goal, swiveling on the half-turn past his marker before slotting a finely threaded through ball for full-back Joel Ward to rush onto.

It was only a small exhibition, but a true sign of what Michael Olise brings to Palace’s midfield. Not many players in Vieira’s weaponry possess the ability to unlock defences at such an alarming rate as Olise.

This is a uniquely and technically gifted midfielder, a delight to watch with the ball at his feet.

If you saw Olise during his Championship days, you’d know he holds a wand of a left-foot possessing the abilities not just to thread deft incisive through balls, but to cross effectively, make the most of set-piece opportunities and also the unique ability to get by a defender with the swiftness of feet and the most deceptive of movements on the ball.

The midfielder recorded an impressive 7 goals and 12 assists in the Sky Bet Championship last season making him one of the division’s most consummate, effective and influential attacking midfielders.

Under Paunovic at the Madejski stadium, Olise fulfilled a variety of roles in attack; on the left-wing, right-wing, centre-midfield and at no.10 highlighting his incredible versatility, tremendous tactical knowledge and awareness but also the superb knack of becoming an influential cog no matter where he is on the field.

Olise was used in Jordan Ayew’s position when he came on, and immediately changed the whole trajectory for Crystal Palace,. The midfielder got his just rewards scoring a scorching effort inside the box past Kasper Schmeichel just eight minutes after stepping on to the pitch.

It’s fair to say Olise has taken in his new surroundings like a duck to water, and his 30-odd minute cameo against Leicester City will have surely captured the imagination of the Palace faithful. They now know they’ve got a real talent on their hands, and that was made perfectly clear when they jeering on his name soon after scoring.

Within those 30-odd minutes, Olise recorded 28 touches of the ball, 2 key passes, 2 long balls, 2 crosses and won 2 of his aerial duels as well as three shots according to WhoScored.com. His pass percentage read at 82.4% meaning he is not afraid to create something out of nothing. If cameos are anything to go by, Michael Olise’s was very impressive.

As much as its easy to get carried away by Olise’s short stint against Leicester City, Patrick Vieira has correctly warned that Olise is not at his best form yet, and that patience must indeed be handed to the youngster as he acclimatises himself to the Premier League, he said:

“We are all really excited by his talent, but at the same time we have to understand it will take time to be a Premier League player. He is working well and hard at a good club to support him to develop himself. It’s about him keeping working, he’s doing well in training, he can score goals, but we have to support him to develop himself.

“It is a long season, so he will definitely play some games. He’s had a long injury and is not at his best yet, but he is improving and will be a really important player for us.”

Michael Olise of course must be given much time to get used to the rigours of the Premier League, though all of his impressive cameos have come against the league’s big boys in Tottenham Hotspur, Liverpool and Leicester City. Yet another stark reminder that 19-year-old doesn’t under the weight of expectation, pressure or lofty responsibilities.

Olise’s future in a Crystal Palace looks very promising, and his performance against Leicester will have surely given Patrick Vieira something to think about heading into the international break; that he isn’t here to sit on the bench, he’s here to make his mark on the biggest stage in the country and boy, does he possess all the tools necessary to become one of the brightest young players this nation has seen.
