Swindon boss Paolo Di Canio called for an investment in new players after seeing his side edge a 1-0 win at bottom club Bury.
James Collins' first league goal for the club sealed the three points, but Di Canio believes his board must invest in players if the club is to challenge for the title.
He said: "I'm happy because we got three points and that's the maximum you can get from a game. But I can't promise the fans now that we'll go up. It's very difficult.
"If we have one or two injuries that's okay, but if we have three or four that's different. It will be very tough to win the league. A team that really wants to go up needs to bring more players in.
"That is the message I send. I will commit 200% because I'm a loyal person, but in the next few weeks somebody needs to say whether they think this is enough. Obviously I think the manager can make a difference and I'm sure I can improve my players. But I'm not God. I am one of the best managers but I'm not God."
Collins put Swindon ahead within 30 seconds with a stunning 20-yard lob, which gave Trevor Carson no chance. Bury rallied and were denied an equaliser by a superb challenge from Jay McEveley just as David Healy got ready to pull the trigger. Meanwhile, a last-gasp block from Matt Doherty prevented Federico Bessone's powerful shot from finding the target.
It meant defeat for Bury boss Kevin Blackwell in his first home game in charge, but he believes the players must take responsibility.
He said: "We missed an opportunity. I said to the players they have to play smart and we got mugged with a goal inside the first 30 seconds. To be fair, we kept going, but we didn't work their goalkeeper enough. Sometimes the players have to take responsibility and certain players didn't do that. I'm not going to accept it.
"I've said to the board we need to change players and some new players are going to have to come in. I'm well aware of what's wrong here and I've been here seven days. Something's got to happen so I've got to change it and I will change it the best I can.
"Some of the signings have been garbage. The jury's out on some of them and I make judgements quickly. Unlike Abu Hamza, who took 14 years, I'll make a judgement quickly and I'll move them out."
