Mourinho confident Crespo's return will be a major success

JOSE MOURINHO is in no doubt about Hernan Crespo's commitment to Chelsea.

The Argentinian is back after a year on loan at AC Milan failed to materialise into a permanent deal.

Milan, who are Chelsea's next American pre-season tour opponents in Boston on Sunday, signed Italian pair Christian Vieri and Alberto Gilardino rather than meet Chelsea's demands for extending Crespo's deal.
