De Jong makes his first training after the transfer to Barca was done

Ajax, after beating Heerenveen in the Dutch cup, trained on Friday morning at De Toekomst. The session began at 11am, with an eye on this weekend's Eredivisie action. On Sunday, they have a big game in Rotterdam against Feyenoord.

Those that started on Thursday did a little less work than the rest. Among them was Frenkie de Jong, who since Wednesday has been a Barcelona player. He will officially make the move in the summer.

De Jong was one of the first to leave Ajax's training ground after the session, while various teammates attended different media. De Jong wound down his window to greet SPORT, a few weeks after our last visit. We invite him to get out of his car and to make a gesture for his new supporters.

And De Jong responded, opening the door and getting out of the car, with a sincere smile, to greet from afar the Barça supporters. "See you soon," he said. After a short chat, he got back into his car and set off.

Surprisingly, he returned a few minutes later and rushed into the building at De Toekomst. He had forgotten a bag and had to head back to the dressing room. After collecting the bag, he dared the car pack on foot, covering himself from the snow, before another friendly wave. He then got back in his car and disappeared.

De Jong, who once again showed his respect towards this newspaper, revealed his excitement to join Barça. It will happen in a few months, although he knows his focus must be on Ajax until then.

RESPONSIBILITY WITH AJAX 

There are some big challenge for De Jong at Ajax in the coming months. And not just Sunday's derby against Feyenoord, his first big test after signing for Barça.

Feyenoord are third in the table, 11 points back from Ajax, who are second, two off PSV. It's Feyenoord's final chance to try and pull themselves back into the title race. There's also Champions League qualification at stake.

Ajax, meanwhile, in the long-term are fighting for the title themselves. They also remain in the Champions League, with a big game against Real Madrid around the corner.
