USMNT star Christian Pulisic told he needs to improve in one key area for AC Milan after stunning Serie A debut

Christian Pulisic's performance on Serie A debut impressed Arrigo Sacchi but the AC Milan legend thinks he can still improve on a key aspect.

WHAT HAPPENED? The USMNT forward dazzled against Bologna which saw himscore a stunning goal and also set up former Chelsea teammate Olivier Giroud for the opener within the first 21 minutes. The 24-year-old joined the Serie A giants after several frustrating seasons in London but started his life in Milan in spectacular fashion.

Former Milan coach, Sacchi, lavished praise on Pulisic for his contribution in attack but pointed out that the winger has room for improvement in the defensive area of his game.

WHAT THEY SAID: “He scored a great goal and I liked how he moved on the wing. He proved that he always knows what to do when he has the ball. This means that he thinks in advance, which is an advantage,” the ex-Italy and Milan boss told Gazzetta.

" (But) He must learn how to help defensively. Tijjani Reijnders is a proper footballer. He did all well. His late runs have the right tempo, he knows when he must play deep or when it’s preferable to play horizontally," he further added.

THE BIGGER PICTURE: Sacchi also criticised Rafael Leao for not tracking back when Milan were chasing the game and opined that Stefano Pioli's men could play more aggressive football by sticking to the 4-3-3 system.

“I was curious to see Pioli’s group and I had some doubts, considering the many new summer signings,” Sacchi said.

“I must admit they played a good game, goals came quite easily and the team dominated. However, I think they can be even more aggressive and press more. If they pick 4-3-3 as their system, wingers must track back more frequently to press the opponents. This wasn’t always done on the left
