Chelsea are excited about the potential of Argie striker Franco di Santo.
Such is the impact Di Santo has made in just six months at the club he is expected to play a significant role in the forthcoming season as one of the back-up strikers.
Blues football chief Frank Arnesen said: "He is closer to being in the first team squad than anyone else at the moment. He has already played at the highest level in Chile so has a very good background. He didn't speak a word of English when he came here, knew nothing about our training methods and still scored many goals straight away."
