The Tottenham Hotspur defender wants his side to balance the demands of three competitions ahead of one of the busiest periods of their campaign.
Spurs host Fiorentina at White Hart Lane in the Europa League for the first leg of their last-32 tie on Thursday night, before big Premier League clashes - one of which comes against West Ham United this Sunday - and the Capital One Cup final against Chelsea.
And Walker has warned his team-mates they have to simply take things a game at a time and not let the prospect of a date at Wembley - possibly even a trophy - distract them.
"Obviously the Wembley game is a massive one for the club and players and hopefully we’re going to get the winners medal," the Spurs right-back told Sky Sports.
“But you have to be professional and we’ve got a lot of games left in the Premier League and games left in the Europa League. We’ll take one game at a time and if we keep doing that, hopefully we will get the rewards at the end of it.”
Having played so many games already this season across four different competitions, Tottenham need every member of their large squad at their sharpest in the coming weeks.
Boss Mauricio Pochettino has not been shy to use all the options available to him this term and having to juggle clashes with Fiorentina with domestic duties will no doubt encourage him to do so once again.
Looking just one step too far, however, could prove costly for Spurs. And history has shown one defeat often has a domino effect in these situations...
