League Cup: Wigan avoid slip-up but Fulham and Stoke make shock exits
Wigan manager Roberto Martinez praised last night's win over Nottingham Forest in the second round of the Capital One Cup but stressed his focus remains on the Barclays Premier League.
The Latics, who have been knocked out of the cup by lower-league clubs five times in the last eight years, avoided an early exit thanks to an impressive first-half performance which totally outclassed their npower Championship opposition.
Martinez made seven changes to the side who beat Southampton at the weekend and was rewarded with an impressive 4-1 by some of his fringe players.
Mauro Boselli opened the scoring for Wigan just over halfway through the first half, powering home a header from Ronnie Stam's cross.
Mayor Figueroa made it 2-0 with a stunning 30-yard rocket into the top-left corner, before Jordi Gomez's strike on the edge of half-time gave the Premier League side a comfortable half-time lead in a dominant display.

Despite avoiding an early banana skin, however, Martinez admits cup success is not a priority next to Premier League survival.
"Playing every week against the best teams in the country is our best cup competition if you want," he said after the match.
"We've got 38 cup finals. Yes, we want to win every game we go into but we need to be able to do it with the full squad.
"The moment we can make seven or eight changes and be able to be competitive that is when I will be pleased and looking to get as far as I can in the cup competition.
Forest boss Sean O'Driscoll admitted his previously unbeaten side had simply come up against a team in irresistible form.
"We had the best chance and then they hit us with two - we're not going to play against that quality in the Championship.
"We've not got carried away with anything - people say we've been unbeaten and performance levels have been really good, but we've no complaints."
