As Barclays Premier League introductions go, Fabio Daprela has surely enjoyed a tougher start to his top-flight career than any other player.
After making his league debut for West Ham United at Chelsea last weekend, the Switzerland Under-19 left-back kept his place for Saturday's trip to Arsenal - the same club he made his first-team bow against in the FA Cup back in January.
While the Hammers have fallen to defeats on all three occasions, the teenager - signed from Zurich's Grasshopper-Club in his homeland last summer - has caught the eye with his tenacious tackling and willingness to run with the ball.
One such run ended in what Daprela believes should have been a second penalty for West Ham at the Emirates Stadium - following the spot-kick awarded when Guille Franco was impeded by Thomas Vermaelen.
"I was running through and I was caught by Alex Song. He didn't get the ball and he touched my ankle. I will look again at the video, but I think yes, it was a penalty."
Unfortunately, referee Martin Atkinson thought otherwise and, with goals from Denilson and Cesc Fabregas coming either side of Alessandro Diamanti's missed spot-kick and Vermaelen's sending-off, West Ham fell to a 2-0 defeat.
With the Gunners down to ten men a minute before half-time, Daprela felt Gianfranco Zola's side could, and perhaps should, have got at least a point from their trip to north London.
"It was nice to play in the Emirates Stadium against Arsenal, that was great, but the result was not so good. I think we should have passed the ball more when we were playing against ten players. We didn't do that, and Arsenal played well with ten men.
"I think when we got the penalty, if we had scored, it would have transformed the game. It would have been possible for us to win the game. With a player more, we planned at half-time to pass the ball and we thought we could still win, but they kept the ball well and made it very difficult for us.
"It's been a great experience. It's nice to play against the big teams - Arsenal, Chelsea and then Arsenal again. I think I have done myself justice, but I can do better."
Having faced two of the so-called 'Big Four' on his first two league appearances, Daprela faces an arguably bigger test when Wolverhampton Wanderers come to the Boleyn Ground on Tuesday evening.
West Ham go into the game a point behind Mick McCarthy's side, and three points above 18th-placed Burnley. As such, a win would provide a huge boost to confidence, as well as three vital points.
"It's very, very important that we win. Now we must get three points. We have to win. We are good as a team and we are confident ahead of these games with Wolves and Stoke, but it's very important that we now win these games.
"It's also very important that the fans are behind us. If they can make a great noise then they can make it very difficult for Wolves and easier for us to win."
