Hodgson will select his 23-man squad, along with seven standby players, on May 13 and Rooney believes the England manager now has a hard job on his hands.
"This was the last squad before the manager names his 23 and I thought it was a good step towards our next get-together," the Manchester United striker said.
"There were 29 of us here and we all wanted to show everyone what we have got. We all wanted to show what we can do and I am sure the manager will have a bit of thinking to do now. He has some tough decisions to make."
