Tottenham star should be on the pitch, not in the stands.
Tottenham Hotspur right-back Kieran Trippier had a game to forget against Manchester United as his errant pass led to the Red Devils' winner.
Meanwhile his potential replacement was left sitting in the stands.
Young star Walker-Peters posted from Instagram at Wembley, showing his view of the game.
He was perfectly placed to see Trippier's pass intercepted by Jesse Lingard, before Paul Pogba passed for Marcus Rashford to score.
Walker-Peters has proved his quality in his recent performances, notably with three assists in the home win over Bournemouth.
Teammate Trippier's form has been on the slide since the World Cup, and he looks like he needs some time out of the starting line up.
Serge Aurier is an option too at right-back, but no more should Walker-Peters be sat in the stands, its time for him to get more chances on the pitch.
