ROBERTO Martinez was in a state of shock after Wigan became the first team to win the FA Cup yet be relegated from English football's top-flight in the same season. A 1-4 Premier League loss away to Arsenal sealed Wigan's fate. Just 72 hours after they beat Manchester City 1-0 in one of the great FA Cup final shocks across London at Wembley, Wigan were well beaten at the Emirates Stadium to join already relegated Reading and Queens Park Rangers in the second-tier Championship next season. Arsenal's victory meant their hopes of qualifying for the Champions League would be in their own hands when they face Newcastle on Sunday's final day of the Premier League season. Two goals from Lukas Podolski and strikes from Theo Walcott and Aaron Ramsey secured Arsenal's victory. But at half-time Wigan were still in the game at 1-1 following Shaun Maloney's equaliser from a well-struck free-kick.

I know we were in a difficult position, but the players are an incredible bunch and they don't deserve this. It's a tough day for the football club. We had an incredible eight years in the Premier League and we need to build for the future," the Spaniard added. You look at the stats and they tell you we conceded far too many goals. Going forward we were magnificent but the number of injuries we've had in the back line is something I've never seen before. Martinez, himself a former Wigan player, insisted the FA Cup had not been a 'distraction' from the business of staying in the Premier League.

It gave us a different sense of confidence. It's great to win the FA Cup. It's an achievement that will live forever. The relegation is something we can rectify. The club is on a fantastic financial footing. We are stronger than ever. It's important we make our fans really proud. They supported us like they always do. It's a difficult time. It's a time to look forward to the future. Wigan Athletic's manager Roberto Martinez applauds his team's supporters after Wigan were relegated from the Premier League as they lost 4-1 to Arsenal at Emirates stadium. While Wigan, four points behind Sunderland with one game left, will be back in the second tier for the first time since 2005, Arsene Wenger's Arsenal team are on course to play in the Champions League for a 16th consecutive season. They had fallen two points behind Tottenham after their north London rivals won at Stoke, but now head to Newcastle knowing another win will guarantee a top four finish. They would not even need three points if Tottenham fail to beat Sunderland at White Hart Lane. "First of all I'm happy we won the game, after 20 minutes we became too conservative and let Wigan back into the game," said Wenger.

But when they (Wigan) got tired after the Cup final, we got a good win as it was becoming difficult for them," the Frenchman added. We've got another big game on Sunday and we'll give it our all again. Meanwhile, Manchester City's first match since they sacked manager Roberto Mancini saw last season's Premier League champions win 2-0 away to Reading thanks to goals from Sergio Aguero and Edin Dzeko. Aguero bagged the first five minutes before the break and substitute Dzeko added a second in the 88th minute as caretaker boss Brian Kidd guided his second-placed side to victory a day after Mancini was fired. Speculation continues to mount over his successor with Malaga's Chilean coach Manuel Pellegrini the red-hot favourite for the post. Alongside the speculation over who would take over from Mancini, another talking point surrounding City was the absence of their skipper Vincent Kompany, said to be suffering from fatigue. Also before kick-off, Manchester City assistant manager David Platt decided to leave the club.
