Switzerland captain Granit Xhaka is full of praise for Arsenal teammates Aaron Ramsdale and Bukayo Saka.
Both players will miss the friendly for England.
Ben White and Emile Smith Rowe could still feature for the hosts as Xhaka acknowledged the absence of the Arsenal pair could help Switzerland's chances.
"Two of them are not playing tomorrow so it's good because we know the quality they have," he said of England's Arsenal contingent.
"Of course they have a very good generation now, playing very well, not only in the national team but with Arsenal as well.
"We're happy that Saka and Aaron are not playing tomorrow.
"We are doing very well at the moment. There are still nine games to play. We have to see what happens in those next games and afterwards you can ask me again how good the season was."
