Birmingham City loan signing Brek Shea says he needs to improve his match fitness in order to make a real impact at St Andrew's.
The United States international, 24, joined on an emergency three-month deal from Stoke and made his debut in the 1-1 draw at Leeds.
"We were a little off at times but that's to be expected as I've just come in," Shea told BBC WM 95.6.
"When we learn more about each other, it'll be a good connection."
Shea, who was born in Texas, signed for the Potters from Major League Soccer side FC Dallas in January 2013 but injury restricted him to five first-team appearances.
He played eight times for Barnsley in a loan spell last season making his debut for the Tykes against Birmingham in a League Cup tie.
"Any footballer just wants to play and it's been frustrating. I've had some setbacks and some injuries but that's all in the past now," Shea added.
"The boys here have been great and every time I train and play with them, I'll learn more."
Meanwhile, Birmingham have taken the former West Ham midfielder Jack Collison on trial.
