Charlton captain Greg Docherty knows the club has a huge three games ahead to finish off their first season back in the Championship. The Addicks are six points clear of the bottom three, but a run of six games without a win has added to the anxiety. Docherty said they've been competitive, but lack the fine margins to win games, particularly at home. Charlton has won eight league games at The Valley, with four draws, including two against top six teams Millwall and Coventry. The club will face Ipswich, who have the worst away record of any top ten Championship teams, on Wednesday. Greg Docherty believes they can beat Ipswich again, having already done so at Portman Road this season. The Addicks will also face Hull on Saturday, before a final day visit to Swansea. Charlton's form in taking points from big teams will be crucial in their bid to avoid relegation. The club's strong end-of-season form under Nathan Jones saw them promoted last term, beating Wycombe and then Leyton Orient in the play-offs. This term, Charlton has shown they can compete against top teams, but need to improve their home form to secure their Championship status. The game against Ipswich will be a tough test, but Charlton has the belief they can win. The Addicks have been guilty of not spreading the goals amongst the team well enough this year, but have the creativity and determination to change that. With their Championship status in their own hands, Charlton will look to give Ipswich the respect they deserve, but also play to win. The mood in the squad remains positive, and they will look to build on their previous win against Ipswich. The Valley will host the crucial game on Wednesday, and Charlton will be looking to get the three points they need to secure their place in the Championship.
