Millwall coach Neil Harris hinted Tim Cahill could make his first senior appearance since returning to the Lions in their Championship clash with Cardiff on Saturday morning (6:45am AEDT).
The Caltex Socceroos striker played and scored for the under-23s in his first game for the club in 14 years on Tuesday morning.
After Cahill watched Millwall’s 2-0 win over Reading and an FA Cup loss to Rochdale from the stands, Harris hinted the 38-year-old Australian could play some role against Cardiff.
“He’s certainly left his mark with his performances in training and his professionalism,” Harris said, according to AAP.
“We saw the team up its performance against Reading. Coincidence? I don’t think so.
“Bringing in the new players, it has given that lift in the dressing room and players who thought they were settled in the team are looking over their shoulders.
“We’ve got quality players to come in and replace them and I’d have no hesitation taking someone out and putting someone else in.”
Cahill said the team is still playing a similar manner to when he left the club in 2004.
"We played similar (last time I was here), 4-4-2, six and eight, wingers, crosses, diagonals, second balls," said Cahill.
"The things Millwall have that always upset teams are energy and intensity.
"Everyone always comes back in some shape or form.
"The staff working around here, the kit man. It will never change."
