Wales manager John Toshack said poor finishing in front of goal cost his side dear in the 2-0 friendly defeat to Brazil at White Hart Lane.

"We had our chances," said Toshack, who saw strikers Rob Earnshaw and Craig Bellamy denied by fine saves.
"More sharpness in the penalty area and we could have had one or two goals.
"But we finished the game strongly and I thought youngsters like Richard Duffy, Lewin Nyatanga and Gareth Bale did very well."
Wales held out until the 61st minute before a stunning 25-yard effort from left-back Junior Marcelo finally broke the deadlock.
There are some positives we can take out of it

Striker Vagner Love added a second 15 minutes from time with a header which gave Wales goalkeeper Paul Jones no chance.
Both goals came during an unsettling period of substitutions, and Toshack said he was disappointed with the performances of some of those players who came on.
"They were fresh and I thought they would've grasp their opportunity better," said Toshack, who sent on Joe Ledley, Sam Ricketts, Carl Fletcher, David Vaughan, Rob Edwards and David Cotterill in the second half.
"The others had played on Saturday as well against the Czech Republic, and we would have looked to some of the lads who came on to have done a little bit better than they did.
"But we take into account the strength of the opposition as well - they're not bad!"
Bellamy's pace caused the Brazil defence problems all night, and the Liverpool striker said Wales will learn from the experience.
"The quality and pace of the opposition can only benefit us, but it was a bit of a shame the way we conceded," Bellamy told BBC Wales Sport.
"There are some positives we can take out of it. They are a very good side and on overall play were probably worthy winners."
