The epic 1970 European Cup final remains a defining moment for both Feyenoord and Celtic, marking a time when these clubs were serious contenders for European football’s top honor.

Wim Jansen’s legacy is tightly interwoven with both teams, thanks to his significant contributions as a player and manager.

Jansen was a key player for Feyenoord during that historic night at San Siro, where they clinched a 2-1 victory in extra time, capturing their first—and still only—European Cup.

Though Jansen passed away in 2022, he continues to be held in high regard by supporters from both sides. In Rotterdam, his status is akin to footballing nobility.

Robin van Persie, who carved out an impressive career himself, has returned to his roots at Feyenoord as a manager. He recently offered a heartfelt homage to Jansen, whom he considered a guiding figure during his formative years at the club.

Robin van Persie spoke effusively about the impact Jansen had on his formative years 

As he looked forward to tonight’s Europa League encounter with Celtic, Van Persie reflected: “For me personally, my journey began in the youth team at Feyenoord Academy.”

‘The first thing I would always do, when I came onto the pitch, was look over to the corner flag on the left side of the clubhouse. That corner was always where Wim was.

‘I always wanted to make sure he was there. Why? Because I only wanted to impress one person, and that was Wim.

‘If I knew he was at the corner flag, then I knew he would be watching. And he was always at all of my games.

‘Wim was the man who triggered me often. He once said to me, when I was a very young player, that he wanted to see in the first five minutes of a game that I was the best of all the players on the pitch.

‘He said: “That is what you have to show”. That was one of those small details when he triggered me.

‘There were so many other moments which we spent together. He once saw me at the bus stop — bus stop 49 — at the back of the training ground behind the stadium. I used to have to travel by metro and by tram to get home.

‘But this time Wim just happened to come by and he let me hop into his car and gave me a lift. The journey was 30 minutes to the other side of town.

‘And during that 30-minute ride, we only spoke about football. And he was asking me so many direct questions.

‘He wouldn’t give me the answer because he wanted me to think. Those questions helped me to become a better player.

‘I have so many memories to think back on with massive pleasure. Wim was such a big football man.

‘Everything has been put into a book, but I don’t need to read it. I have the rough version of all his transcriptions at home which were given to me, and I still read them now.

‘Everything he wrote down shows the passion and love he has for football, and I feel that whenever I read it.

‘That’s why he was so important in that one year at Celtic, too. That’s why he has been such an important figure in Dutch football.’

The notes scribbled down by Jansen over many years have been passed to Van Persie. With Feyenoord currently mired in a run of poor form, they become a source of knowledge and comfort in difficult times.

‘I was very honoured,’ continued Van Persie. ‘I got part of his legacy from his son, Wim Junior.

‘I read so many pages and still look at them now. Everything is made so clear, whether it’s about technique or tactics. Wim had written pages and pages on it all.

‘But, then again, he was always full-time busy with football. Anything that came to his mind, he wrote down.

‘Wim has been an icon for Dutch and Scottish football because of that year he had with Celtic.

‘In this way, I feel we are playing a game against Celtic which, in my opinion, is actually in honour of Wim Jansen.’

Looking back now, those were the glory days for Celtic and Feyenoord in the late 60s and 70s. Both clubs conquered Europe and both wear those victories as a badge of honour.

Dotted around De Kuip Stadium here in Rotterdam are countless murals and all kinds of memorabilia in testament to Feyenoord’s finest hour.

Yet, the landscape is very different now than it was all those years ago. The prospect of winning another European Cup is little more than a fantasy.

In this port city where shipyards are still a prominent part of the culture, theses two clubs are scratching around just trying to stay afloat in the Europa League.

Martin O’Neill arrives in Rotterdam still steering Celtic’s ship, before the expected handover to Wilfried Nancy early next week.

Celtic are now in the final stages of negotiations with Nancy and it is expected that the 48-year-old Frenchman could be in the crowd to watch Sunday’s match against Hibs at Easter Road.

O’Neill spoke earlier this week of his belief that Nancy will be afforded a fresh start and should not be affected by the off-field mutiny which continues to plague Celtic and linger like a toxic smog.

There will be much to occupy him once he gets started. Over the next month or so, Celtic will play a Hearts side who sit top of the table. They have a League Cup final against St Mirren. They also have two home matches against Aberdeen and Rangers.

Those games on the domestic front will shape the early weeks of the Nancy era at Celtic Park. But whether or not there will still be a European campaign will depend on Celtic’s ability to rouse themselves in Rotterdam.

Defeat to Feyenoord could well sink Celtic’s hopes of progression in what has been a dismal European campaign.

Roma would then be next up in Glasgow in a fortnight. Flying high at the top of Serie A, few would give Celtic much of a chance in that one.

Much will hinge on their ability to take something tonight against a Feyenoord team who actually sit a point behind Celtic and have won only once in their last five matches in all competitions.

De Kuip is one of the great cathedrals of European football. A seething cauldron of riotous noise and colour, it can be a daunting venue for even the very best teams.

The thunderous acoustics and pre-match ritual of pumping Dutch techno music over the PA system is usually an assault on the senses.

O’Neill enjoyed many great European nights with Celtic during his first spell in charge. He restored the club’s credibility in the Champions League and the old UEFA Cup.

He is now on the home straight, the epilogue of his second coming. Victory in Rotterdam would be one hell of a last hurrah.
