Crossing the Divide

Football keeps a sliding scale of forgiveness. Leave for money and you're grumbled about for a transfer window or two. Leave for a manager who actually picks you and, in time, you're understood. But cross the divide, sign for the club your club exists to beat, and the scale snaps. Twenty years on, grown adults are still booing a man in his fifties for appearing on television.

The strange part is how unevenly the sentence gets handed down. Some crossings harden into permanent hatred. Others are shrugged off within a season. And the difference, on inspection, has remarkably little to do with the player.

Campbell, and the walk that never gets forgiven

Ask who has played for both Arsenal and Tottenham and one name arrives before the question has finished. Sol Campbell was Tottenham's captain, their best player, the one fixed point a struggling side could be built around. He let his contract run down, and in the summer of 2001 he appeared at a press conference in an Arsenal tracksuit. On a free. Spurs received nothing.

The destination was only half the offence. The manner was the rest. Supporters felt they'd been assured he was staying, then watched him join the one club he could not join. The Judas banners wrote themselves, and they've never really come down.

From Campbell's side of the fence, of course, the move worked completely: two league titles, an entire unbeaten season, a goal in a Champions League final. As a footballing decision it stands among the best any defender has made. Tottenham fans know that, which is precisely why it still stings.

Yet the same divide has been crossed gently. Pat Jennings kept goal for Tottenham for more than a decade, was moved on when the club decided he was finished, and gave Arsenal several excellent years, cup final included. Both ends adore him. William Gallas went directly from one to the other in 2010, a former Arsenal captain no less, and drew little beyond grumbling. Emmanuel Adebayor arrived at Spurs having once sprinted the length of the Etihad pitch to celebrate in front of the Arsenal supporters, and even that had softened into pantomime by the time he pulled on white. Same divide. Wildly different sentences.

Tevez and the poster

Carlos Tevez gave Manchester United two seasons, league titles and a Champions League. United dithered over signing him permanently. City did not dither. In 2009 he went across town, and City put him on a sky-blue billboard bearing the words "Welcome to Manchester", which remains the finest bit of needle any marketing department has produced.

United's fans were furious, and then, rather quickly, they were not. The anger burned hot and went out. Tevez had been there two years. He wasn't a homegrown boy, hadn't kissed the badge for a decade, and the club had visibly hesitated over him. The story supporters told themselves was that a mercenary had done mercenary things, and that story requires no lifelong hatred. It barely requires attention.

Mo Johnston, hated twice over

For the unabridged version, go to Glasgow. In 1989 Mo Johnston, a former Celtic striker and a boyhood Celtic man, was paraded as re-signing for Celtic. Weeks later he signed for Rangers instead. Graeme Souness had pulled off the most inflammatory transfer in British football, and Johnston became the first high-profile Catholic signing for Rangers in the modern era.

Celtic supporters saw betrayal. A section of Rangers supporters saw contamination, and some burned scarves and season tickets outside Ibrox rather than accept him. One transfer, two enraged sets of fans, and a player who could no longer safely drink in half the pubs of his own city. He scored plenty for Rangers, including against Celtic, and won some of them round. But Johnston is the rule at its purest. The Old Firm divide was never about football, so crossing it was never going to be judged in footballing terms.

Figo and the pig's head

Luís Figo was Barcelona's talisman, the player the Camp Nou sang for. In 2000 he joined Real Madrid for a world record fee, the centrepiece of Florentino Pérez's presidential campaign. Barcelona's supporters didn't merely lose their best player. They lost him to the rival, as an election promise, and they learned that their hero could be bought like anyone else.

The rage ran for years. Every return to the Camp Nou became an occasion in itself, the whistling so loud the football turned incidental, and in 2002 it produced the image by which the whole affair is remembered: Figo standing over a corner while a pig's head lay on the turf near the flag. Not thrown at treachery in the abstract. Thrown at the man they'd loved most.

What actually decides it

Set the cases side by side and the pattern has nothing to do with talent, or even with the size of the rivalry. It's about investment. Campbell was the captain they believed was staying. Figo was the icon of the entire club. Johnston was one of their own, twice over. In every unforgiven case the crime is identical: the supporters had made the player part of who they were, and he demonstrated that, for him, it was a job.

The forgiven crossings are the ones where nobody had made that mistake. Tevez was passing through. Gallas was a known grump in transit. Jennings was let go rather than leaving, so the guilt sat with the club and not the man. Denis Law backheeled a goal for City against United and refused to celebrate it, and United's fans loved him anyway, because everyone present understood where his heart was.

Which is to say the fury was never really about the player. It's about us. What supporters cannot forgive is not the crossing but the disclosure that comes with it: that the love only ever ran one way. The player changed jobs. We'd built a shrine. And that, more than any tracksuit or billboard, is why a man in his fifties still gets booed for doing punditry.

Reckon you'd spot them from the clubs alone?

A career like these makes a fine puzzle. The clubs are revealed one at a time, and the earlier you put a name to them, the more you score. Some careers give themselves up inside two clubs.
