Wigan Athletic boss Roberto Martinez says Liverpool players struggle when they're under pressure.

The Latics enjoyed a crucial win over the Reds on Monday.

"I wouldn't say it was a surprise they struggled," said Martinez.

"When you put that extra pressure on Liverpool, everyone wants to beat them and with their style people can work tactically against that.

"You always get good and bad performances but I think the Premier League is extremely exciting this season: three teams competing for the title, four teams for fourth place and eight teams to avoid relegation."
