However, he is expected to join the team in the coming days.Broja had a remarkable season-long loan spell at Southampton last campaign and will be hoping to replicate such form with the Blues. He scored nine goals in all competitions for the Saints, making well up to 32 league appearances.The departure of Chelsea striker Romelu Lukaku to Inter Milan on loan this summer could create an oppurtinity for Broja to make a claim for first-team football.Frank Khalid@FrankKhalidUKWe have spent crazy money trying to find a striker who could score goals, I would give Armando Broja a chance, he has the right mentality, physical strength, speed, & knows how to get the ball back of the net. With the 5 sub rule what harm will it do having him in our squad?88076We have spent crazy money trying to find a striker who could score goals, I would give Armando Broja a chance, he has the right mentality, physical strength, speed, & knows how to get the ball back of the net.

Broja could possibly use the pre-season to find out his fate in the Blues' team.
