Portugal vs Wales Prediction and Tips: Corners

Wales's wide players, Portugal's blunt possession and where the corners come from

Corners are a by-product of two things: crosses that get blocked and shots that get blocked. Both require players in wide areas, so the first question in any corners market is which side is actually going to attack from the flanks. Portugal have the better wingers by a distance, and full-backs who overlap rather than tuck in. What the numbers say, though, is that Portugal do not turn that width into corner kicks anything like as often as the reputation suggests.

Across their last twelve internationals Portugal have won 5.7 corners a game. That looks healthy until you see which matches produced them. The ten in Dublin and the nine against Croatia came in games Portugal had to force. The games against opponents who simply sat in produced three (Uzbekistan), three (Nigeria) and five (Congo DR). Against Uzbekistan, Portugal had 17 shots, nine on target and 65.9 per cent of the ball and still won only three corners. A side that plays through the middle and finishes its moves does not accumulate corners; a side that keeps hitting a wall does.

The other half of the equation is what Portugal concede, and here the distribution matters far more than the mean. The mean is 3.3 corners against per game over those twelve matches. But six of the twelve opponents won four or more, and the six that did not were Armenia, Mexico, the United States, Chile, Nigeria and Uzbekistan. When the opposition cannot get out, Portugal give up nothing. When the opposition can carry the ball forward at all — Hungary, the Republic of Ireland, Colombia, Croatia, Spain — Portugal have conceded between four and seven.

So which Wales turns up. Craig Bellamy's 28-man squad, named on 15 September, is stacked with wide players: Dan James, Harry Wilson, Sorba Thomas, Wes Burns, Brennan Johnson and David Brooks in the forward areas, with Neco Williams, Connor Roberts, Jay Dasilva and Rhys Norrington-Davies for the wing-back and full-back roles. This is not a squad assembled to sit in a flat 4-5-1 and clear it long. Wales have won at least five corners in every one of their last ten matches for which ESPN recorded the data, 7.7 a game, and that run includes both fixtures against Belgium, in which they were the underdog and lost: five in Brussels in a 4-3 defeat, seven in Cardiff in a 4-2 defeat. They cross, the crosses get blocked, and the flag goes up.

Game state cuts both ways here and it would be dishonest to pretend otherwise. If Portugal are two ahead inside half an hour, one of two things happens. Either Wales are forced to come out, which pushes their corner count up, or Wales settle for damage limitation and spend an hour without the ball. Portugal's own number is the more predictable one in that scenario: they drop the tempo, the game flattens and the corners dry up, which is broadly what happened against Uzbekistan.

The lines on offer look like the output of a sensible model rather than a read on this particular match. The match total sits at 9.5, almost exactly Portugal's twelve-game average of 9.0 corners per game. The Portugal team line is 5.5, again close to their own average. The Wales team line is 3.5, and that is the one worth arguing about.

Team news

Wales named a 28-man squad on 15 September for the two away fixtures against Portugal and Denmark. Harry Wilson and Jordan James return after missing June, and Cardiff City's Cian Ashford has a first senior call-up. The wide department is fully stocked: Dan James, Sorba Thomas, Wes Burns, Brennan Johnson and David Brooks further forward, Neco Williams, Connor Roberts, Jay Dasilva and Rhys Norrington-Davies behind them. The FAW listed no withdrawals or injuries alongside the announcement.

Portugal's call-up could not be verified from an official source — the FPF site refused our request — so the wide options referred to above are taken from ESPN's Portugal squad listing rather than a confirmed announcement. Treat the individual names as provisional. No referee appointment and no UK broadcaster had been published at the time of writing.

Verdict

Wales over 3.5 corners is 2.02, the under 1.66. Strip the margin out of that pair and the market is pricing Wales to win four or more corners at about 45 per cent. That is the number I want to argue with.

Wales have not been held to three or fewer corners in any of their last ten matches with recorded data, and the two closest analogues in that sample — underdog, beaten, away and at home to Belgium — returned five and seven. Set against that, Portugal's record in Lisbon, Porto, Leiria and Oeiras is genuinely tight: ten corners conceded in four matches. But those opponents were Hungary, Armenia, Chile and Nigeria, and across the full twelve-game sample half of Portugal's opponents still reached four. My own estimate for Wales is a corner count of around 4.2. On a Poisson basis that puts four or more at roughly 57 per cent, and corner counts are a little more dispersed than Poisson assumes, so call it 55.

Fifty-five per cent against a market price of 45 is an edge of ten points and about 11 per cent expected value. One unit at 2.02, and I would still take it down to 1.90 and no lower. The first-half version of the same idea — Wales over 1.5 corners before the break at 1.95 — is the same argument with half the time in which to be right, so I will take the full ninety minutes.
