Aston Villa manager Martin O'Neill believes Brad Guzan will develop into a quality goalkeeper.
The Villa shot-stopper became a claret and blue hero when he saved four penalties during a Carling Cup shootout against Sunderland earlier in the season.
However, Guzan did not have the best of games in the second leg semi-final against Blackburn on Wednesday, conceding four goals as Villa booked their place at Wembley.
With Brighton travelling to Villa Park in the FA Cup on Saturday, Guzan may keep his place in the starting XI but, although O'Neill would not be drawn on his selection, he believes the American will become an excellent keeper.
"Do I still have faith in Guzan? I wouldn't want to be commenting in terms of the performance of players. I would kind of leave that to the side," he said.
"But I do know that Brad Guzan, in my view, will be a real quality goalkeeper.
"It is always difficult for a player coming in and needing to perform when you haven't had a host of games behind you. That is difficult.
"But his performance in the Sunderland game was fantastic. It was a big reason why we got to the quarter-finals - and now we are in the final.
"But there is no point in you asking if he will play on Saturday."
O'Neill has revealed he will make changes for the cup clash, with Emile Heskey (foot), Richard Dunne (hamstring) and Stiliyan Petrov (Achilles) all doubtful.
"I will change the side around. Playing three games in six games has taken its toll and I've got another group of players I am going to rely on to get us through this tie," he added.
"We've got one or two younger players around that did well in the Peace Cup in the summer (in Spain) and who are desperate for a chance and some who are currently unlucky not to be in the team.
"But I will make them fully aware of Brighton. I saw them last week against Walsall and they played well in really heavy conditions. If they perform like that, they will cause us problems.
"We've got the home tie but Brighton are bringing around 6,000 fans and it will be a tough afternoon for us.
"But with that result and performance against Blackburn, and everything that game entails, whoever takes the field on Saturday should be ready - whether they have played the last couple of weeks or not."
