(Reuters) - Belgium international Romelu Lukaku said he has evolved since he last played in the Premier League two years ago and has returned to Chelsea as a more complete player. Lukaku was Inter Milan's top scorer -- with 24 goals -- in Serie A last season, leading them to their first Scudetto in 11 years. After leaving Chelsea, Lukaku switched to Everton before signing for Manchester United in a big-money move in 2017 that ended in disappointment. Lukaku added that he likes manager Thomas Tuchel's system and is prepared to adapt. Lukaku was unavailable for Chelsea's 3-0 win against Crystal Palace over the weekend but is expected to feature against Arsenal on Sunday.
