The midfielder has had a whirlwind spell after completing his transfer from Ajax last week before competing in two UEFA Nations League matches with the Netherlands.
Following his involvement in the internationals with Poland and Italy, he has been able to link up with the Reds to prepare for the start of the 2020/21 Premier League season.
The midfielder was given an emotional send-off by Ajax supporters in Amsterdam and has left with the sincere best wishes from everybody associated with the Dutch club.
Now he is fully immersed in life in Manchester and took part in training on Wednesday, as our photographs illustrate.
