FC Dallas goalkeeper Richard Sanchez enjoyed his six-day trial with Chelsea.
The Mexico U17 international has now returned to the 'States after his tests.
"It was just a week which included three workouts with the first team before the quarter finals of the Champions League and six practices with the Chelsea Academy, but the learning experience is priceless and interest more real than ever.
"While there I learned a lot, to be training with him (Petr Cech) was very important.""I felt pretty good, at first I was very nervous about being with the first team at Chelsea, but training for the week I adjusted a bit and I felt good. It was a great experience training with Petr Cech, John Terry and all the others," he said.
