Christopher Nkunku to boost Chelsea's £30m transfer plan that has worked in Premier League

There was so much excitement surrounding Nicolas Jackson when he first put on a Chelsea shirt during pre-season in the United States. A lot of Blues supporters had never seen the 22-year-old striker kick a ball before and their desperate need for an accomplished No.9 saw a lot of expectation immediately fall on his shoulders.

Jackson was scoring for fun in pre-season, where he linked up well with the now-injured Christopher Nkunku. And Chelsea supporters were backing the Senegal international for a breakthrough debut season in the Premier League.

However, after a promising performance against Liverpool, but no goal, and a similar display versus West Ham United a week later; there were already questions being asked over whether Jackson is the right man to take on such responsibility at Stamford Bridge. Luton Town came to west London the following week, though, and it was a big moment for Jackson.

He tapped in Raheem Sterling's cross to ensure the first three points of the Mauricio Pochettino era at Chelsea over the newly-promoted Hatters. «We knew Nicolas Jackson's quality when we signed him, we saw that before,» Pochettino said on his new striker to Sky Sports.

«It is not that we ask him to run and press the ball, he is quality in the way he recovers the ball, but he can also finish. It is only a matter of time, once he settles into the Premier League, he will show it more.

»Nicolas Jackson has top quality. I have no doubt that he can become one of the greatest strikers in the Premier League."
