The Hammers stunned the holders with a 4-0 thrashing that has propelled them into the semi-finals of the competition for the first time in over 20 years. More importantly, Grant hopes their second successive triumph will inspire their Premier League survival bid. Sunderland are their next assignment on Sunday and Grant has urged his players to continue their revival. "It's very important for us to build a winning mentality and the best way to do that is with wins like last night," the West Ham boss told talkSPORT. "The way that we did it was amazing. Last night was great football. "Other than the poor performance at Liverpool and the second half against Newcastle, we've played well. "We've also played better than our opponents in 90% of games. "But we didn't win and sometimes the players doubt what we need to do. "We did not need to make any big changes but continue playing this football, improving a few things, and they did it yesterday and last Saturday against Wigan. "I can't say that Saturday was a better game than the one before but we were more clinical and it's very, very important to continue this progress." Carlton Cole scored twice in the second half, lifting the England striker's tally to three goals in 19 appearances this season. The 27-year-old has been criticised for his recent form but Grant believes he is starting to impress once again. "Carlton lost a little bit of his confidence and was not fully fit on the physical side as well," he said. "But in the last few weeks he's been working really hard and I'm delighted. We need him because he's a good striker."
