The forward is confident that pairing the midfielder with Cesc Fabregas will allow the Blues to dominate this season
The arrival of Jorginho from Napoli has equipped Chelsea with one of the best midfields around, according to Alvaro Morata.
The Brazilian-born Italy international moved to Stamford Bridge last month, having been heavily linked with Premier League champions Manchester City.
He has been joined in west London by his former Napoli boss Maurizio Sarri, who replaced Antonio Conte.
And former Real Madrid and Juventus striker Morata feels Jorginho will prove to be a key acquisition as the Blues, champions in 2016-17, seek to improve on a disappointing fifth-place finish in the league last season.
