Wales manager Chris Coleman says he is not surprised that counterpart Roy Hodgson has opted to take teenager Marcus Rashford to the Euros.
"I'm not surprised, I've watched him a lot and he is a class act," he said.
Coleman, who opted to pick Joe Ledley in his 23 man squad despite him suffering a broken leg on 7 May, says it is difficult to predict how Rashford will perform under the pressure of a major tournament.
"Some players go into the tournament on fire and they fall flat," he said.
"You see others come from nowhere, like (Salvatore) Schillaci for Italy in the 1990 World Cup and bang the goals in.
"It is hard to call it. Ability-wise, he is a good player, and has a real good mentality.
"I couldn't say what to expect. As soon as he's there he will have to adjust, as we all will."
Coleman, who signed a new two year deal to remain as Wales boss in May, believes star striker Gareth Bale has a key role to play in removing Wales' pre-Euro 2016 complacency.
"I thought 'cheers for that, a semi-final just will not do'," Coleman said. "That is the mentality we want. The mentality of achievement.
"Since we qualified if you look at our results it is nothing to shout about."
"We went through a run of results where we were almost unbeatable, but we have tailed off a bit," he continued.
"I'm not making any excuses - we haven't had this one, we haven't had that one.
"It's international football, you get on with it, but sometimes with success comes a little bit of complacency.
"Subconsciously sometimes, but we are our best when we are right on it."
