The reason we won't achieve our xG is because we have the lowest budget in the league and our players are not capable of producing worldies on a regular basis.
The goal that Tielemans scored against us was an absolute belter, and he's capable of doing that from time to time. I don't see any of our midfielders doing that more than once a season, let alone Tielemans doing it twice in a month (against Man U and against us). But that's the difference between most other Premier League teams and ourselves.
That's why we rely on a lot on teamwork, workrate, and hoping that we create sufficient chances for us to convert them. Don't forget, we've clearly focused on set-pieces, because the management will have looked at our squad and seen that our ability to convert chances in the Prem will be lower than in the Championship.
It's great that we have a team that works so hard, plays some decent football, and does create chances, but we're not going to convert chances in the same way that we did in the Championship.
Toney is learning his trade against superior defenders, Mbeumo's not the best finisher but his movement is excellent, and our midfielders aren't regular goalscorers, so we will struggle for goals.
So long as keep creating chances, we give ourselves more of a chance of getting some kind of result, and I suspect that by the end of the season, we will have converted enough of those chances to stay up. If we can keep on improving the squad, then who knows what will happen next season?
And that's why xG is important. It's a measure of performance, and an indicator of what we might achieve given a level playing field. Our recruitment team will be looking to close the gap between our results and our xG, focusing on converting chances, and then we'll be able to dream of a European tour.
