Stoke Highlight the Art of Crossing.
Two Stoke City games, two headers, two goals and a duo of 1-0 wins not only demonstrates the fine lines that can separate six points from two in a low scoring sport, such as football, but also the important role still played by crosses in the modern game.
Lavishly assembled squads may partly spurn crossing as a primary route to goal in favour of more intricate, possession based passing sequences to create space before the final delivery, but even the likes of Arsenal when faced with the need for a goal do fall back on the traditional cross.
33 crosses yielded a single goal in a recent 2-1 home defeat for Arteta’s side against Wolves and infamously, Manchester United attempted over 80 crosses in a drawn game with Fulham in the last days of David Moyes’ reign.
Crossing, as a primary strategy reached a low point with Liverpool’s 2011/12 team consisting of a big target man, Andy Carroll and a host of players ready to deliver a cross, led by Stewart Downing.
Unfortunately, such a predictable game plan & and tendency to cross the ball early from less advanced field positions, resulted in a failed experiment. An average of 21 Liverpool crosses per game was rewarded with just four Premier League goals.
Present day Liverpool lead the analytics revolution, but their failed, decade old legacy helped to kick start that revolution, as data was used to explain why their cross heavy approach failed and where the lesson lay for teams to maximize the returns from a wide player’s staple delivery.
Crosses in general are inefficient.
Leagues vary, but as a baseline number, it takes upwards of 90 crosses to score a goal directly from the delivery. Secondary chances created after the initial header or shot, but during the same phase of play, improves the strike rate to around one goal every 50 crossed balls.
However, not all crosses are equal. The danger is more apparent if a side works a delivery from the byline compared to a last-minute desperation hoof from deep into the mixer.
Fortunately, data can differentiate between types of crosses. Whether the ball was chipped or driven on the ground, for example. But where crosses originate and where they are aimed provides the biggest insight into how to turn a cross into a winning formula.
You can divide the origin and intended destination of a cross into two broad categories depending on how effective they are at producing goals.
In the graphic below, prime areas are shown in red and the least effective in blue.
Blue wasteful target areas are intuitive.
If the ball is aimed too close to the goal line, they become prey to a dominant keeper. But place the cross too close to the edge of the box and any shot or header will be taken from distance and for every yard a striker moved away from the goal, the likelihood of a goal falls by ten percent.
The red sweet spot is between these two areas.
The touchline hugging, wasteful blue delivery areas give both the keeper and defenders time to defend the box, whereas moving infield to deliver the cross reduces defensive reaction time and greatly improves conversion rates.
Hitting a ball from a wide and deep wing position to the wasteful area of the six-yard box, going from one blue zone to another, only produces a goal every 500 attempts. Whereas a delivery from a red, prime infield area to a red, prime area of the box increases conversion rates to around one goal every 20 crosses.
Stoke City’s two winning goals against Wycombe and Middlesbrough have been added to the graphic and hit the sweet spot for both Fox & McClean’s delivery and Collins & Powell’s headed goals. They were assists that were drawn from the most productive area of the crossing playbook.
Of course, there’s much more than “crossing by the numbers” to a successful outcome.
Powell is an accomplished header of the ball. During his Championship career over 20% of his goal attempts have been from headers and he is adept at getting on the end of higher quality attempts than the league average. Whilst Collins’ physical attributes are obvious.
Campbell then crossed from one prime area to another for Cardiff to obligingly smack the ball into their own net, before he departed on a season long, injury induced hiatus, Fox hit the prime red zone with a pacy cross to defeat Blackburn & Brown repeated the prime to prime connection to set up Thompson to briefly draw level with Spurs in the Carabao Cup 1/4 final.
Clever off the ball running also contributes, a seen by Vokes drawing away Wycombe defenders with his near post run & Stoke creating an over load of far post attackers for the goal against Middlesbrough.
Over recent games, Stoke City had the crossing basics in place and good things followed,
On the weekend when Stoke climbed into the playoff spots on the back of two smartly executed crosses, Arsenal in the North London derby were again trusting more to luck by throwing in another 44 crosses in the vain pursuit of a goal.
