Manchester City manager Manuel Pellegrini believes midfielder Fabian Delph can make a big impact when he returns from injury.
The 25-year-old suffered a hamstring injury on his City debut last month in Melbourne and will miss Monday's Premier League opener at West Brom.
But the Chilean believes the £8m signing from Aston Villa will be back in action before the end of August.
"I think he needs 15 days more - that will be a month," he said.
"He played just 17 minutes but you saw in those 17 minutes that he will be an important player for this club."
