He may have failed in the EPL, but Lukaku has proven himself worthy of trust at several clubs. Napoli is one of the teams that has been able to make good use of him. He has a large frame and good body balance, making it difficult for defenders to mark him effectively. The news of his injury and the possibility of surgery will be a blow to Napoli. They can take advantage of the transfer window, which is still open. It is reported that they are interested in signing Hojlund. Hojlund may leave because he was not included in the squad for Manchester United's first match.
No doubt with Romelu Lukaku potential for Serie A team, indeed failed with premier league team but helping Inter Milan and Napoli winning the Scudetto although he can't did when playing for AS Roma. Under Antonio Conte tantician, Romelu Lukaku always get regular position last season with Napoli and his contribution helping his team winning Scudetto and next season will participants at UEFA Champion League. Lukaku seems easily for adapting well with Serie A teams although he had played for three difference teams from Inter, Roma and Napoli but keep consistent performing well every season.
I don't heard yet rumor about Napoli will sign Hojlund from Manchester United although that player have loss regular position but Napoli for awhile have many top striker. If can sign Hojlund giving advantage for Napoli because have many match to play for next season after participating at Champion League and Antonio Conte have many option when rotating his players.
