West Bromwich Albion manager Tony Mowbray paid tribute to the quality of the Coca-Cola Championship after a weekend of FA Cup surprises.
Mowbray's side became the third team from the second tier to reach the semi-finals of the competition after comprehensively negotiating a potentially tricky quarter-final at Bristol Rovers with a 5-1 victory.
Earlier yesterday, Cardiff had knocked out Premier League opposition in the shape of Middlesbrough, while Barnsley sensationally upset the odds to beat cup holders Chelsea 1-0 at Oakwell on Saturday.
Mowbray said: "The draw will be a very exciting one with none of the big boys left in there. Portsmouth are the only Premier League side still left in the competition and they are a good side.
"I think the fact that they are the only top-flight side remaining is a good advert for the Championship. You can see by the quality of the teams that have progressed this far in the competition that it is a hard league and a league with a lot of very good sides.
"It makes a change that none of the big teams are still left in there and it has presented a real opportunity for someone."
With the semi-finals being staged at Wembley this season, Albion are set to return to the scene of their play-off final heartache for the first time since losing to Derby in May.
Mowbray hopes his side will be able to avoid disappointment this time round. He said: "We were there last year and we had a defeat so this time we will be looking to enjoy a victory. I have no preference about who we might play. It will be a terrific occasion no matter who we get."
Opposite number Paul Trollope insisted his team could be more than satisfied with their efforts in the Cup this year after the club equalled its best run in the competition.
He said: "I am proud of the players. We have done fantastically well to get this far - and you have to remind the players of that because they are bitterly disappointed to miss out on a semi-final spot."
