James, who spent seven years in Liverpool and was capped for England 53 times, said that the marquee signings of the ISL teams have been giving their best.
"Naturally, there are lot of expectations from the marquee signings. But they have come here at late stages of their careers. You should not expect Alessandro del Piero (Delhi Dynamos) to play like he did at the height of his career," James said ahead of his side's ISL fixture against Delhi Dynamos tomorrow.
James also said that the ISL has been fantastic so far and it has been a great experience personally also. He said the only drawback of the league was the hectic schedule.
"It has been fantastic so far for a first-time league. It was amazing for 50,000 people turning up in Kochi for our match. Maybe, the schedule is tough as we are even playing three matches in seven days and so it is affecting on the players," he said.
