The Japanese youngster has been a hit in Lancashire since linking up with Owen Coyle’s side in January, producing a string of exciting displays on the left flank.
Ryo has been at Bolton during a difficult period - he was on the pitch when Fabrice Muamba collapsed at Tottenham - and Walcott thinks his club-mate has coped well in the circumstances.
“Ryo has done very well at Bolton,” he told Arsenal.com.
“It is hard for such a young kid to go there and do what he is doing, showing no fear with everything that happened at Tottenham [with Muamba]. It is hard and it has probably hit him definitely.
“He will be a better person for it, a better player and I can see him coming back here next year and playing a lot more regularly.
“The way he is playing, there are full backs out there now who are thinking, 'I don't want to play against him this week'.”Copyright 2017 The Arsenal Football Club plc.
