Malky Mackay is still hopeful of adding to his Cardiff City squad before the end of the transfer window after the club's opening-day defeat.
The Premier League new boys found themselves on the end of a 2-0 defeat to West Ham in their season opener on Saturday, and Mackay knows work still needs to be done to enable the team can compete in the top flight.
The Scot gave debuts to Steven Caulker and Gary Medel at Upton Park as goals from Joe Cole and Kevin Nolan gave West Ham all three points.
Mackay has made four new signings during the close-season, but after missing out on Etienne Capoue to Tottenham, acknowledges his search for new recruits continues.
"We're certainly trying but so is everyone in the Premier League," he said. "We're trying to get good players but sometimes it's not always within your control.
"If I find a good player and everything comes together in terms of the club agreeing and the player agreeing then I'll absolutely try to act."
The Bluebirds looked in need of fresh impetus at Upton Park, but Mackay believes improvement is simply a case of his side learning to be more ruthless.
"Overall I can't be too harsh on my players because on a day at Upton Park I thought we had an awful lot of posession and gave a good account of ourselves," he continued.
"It needs to be better but we're away from home against a good team. They were clinical with their two finishes and we weren't.
"I don't think it's a lesson because we knew before that we had to be clinical, it's about choices and that final pass."
One of Cardiff's new arrivals is Andreas Cornelius. The striker was not available for the West Ham clash as he recovers from an ankle injury, but Mackay is positive the 20-year-old will soon be back in training.
"He (Cornelius) joined in (training on Friday) but wasn't quite match fit," the Scot added. "He was nearly ready but he should be back training next week."
