As Eddie Nketiah and Dani Ceballos have shown, a lot can happen in seven days.
Our duo were involved in a pre-match clash ahead of last week's win at Fulham but combined on Saturday to secure a dramatic win over West Ham United at Emirates Stadium,
And Nketiah insists there's no bad blood between the two of them.
"There was a bit of a coming together [before the game against Fulham], I was a bit upset with the challenge," he said. "But we made up pretty quickly and we got on with it.
"It was a great pass [from Dani] across, good vision from him, I just tried to stay onside and make sure I was behind the ball. It was a pretty easy finish from there, but it was a great ball.
"I just want to keep trying to help the team and improve as a player. To come on and get the winner is obviously a great feeling. I'm delighted with the three points.
"West Ham made it very difficult. In the second half they came out really strong. We had to keep going, we knew it was going to be a patient game, we had to keep passing it, keep moving it. The chance was there at the end and luckily I put it away."
