Paul Scharner has told his Wigan team-mates that they can't keep losing leads in matches or they will end up in the end-of-season relegation battle. For the second time in the space of three days, Latics lost a lead and had to settle for a point after a 1-1 draw with Stoke at the DW Stadium on Tuesday night. The midweek result means there has been seven matches this season that Roberto Martinez's side have failed to win after scoring the first goal – with the latest result leaving Wigan in 16th, just one point outside the relegation zone. Wigan's inability to hold on is putting the club's top-flight status in jeopardy, according to Austrian international Scharner. The midfielder admitted: "We're in the middle of a relegation battle, and in these types of games we should be looking to come away with all three points. "It's in the second half where our problems lie - we can't seem to sustain the performance over 90 minutes. We have to keep our opponents under pressure for the whole game, and I think that should be our focus now for the rest of the season." Wigan’s next Premier League game is crunch-clash with local rivals Bolton at the DW Stadium on Wednesday February 17, followed by a home game against Tottenham next Sunday.
