Manchester City boss Sven Goran Eriksson is delighted with the progress of Nery Castillo and Felipe Caicedo.
"They will both get better and better the longer they are here though we may not see the best of them until next season," he declared.
"They are learning fast but you have to remember Caicedo is very new to this country and has been here only one month whilst Castillo has not had much football at all since he left Olympiacos last summer.
"He was also away for six weeks with his shoulder injury but both of them could play an important part in what we are trying to achieve."
