before sealing his move to City earlier in July.
He has made an instant impact at right-back, his surging runs down the right an already familiar sight, and he will be looking to use everything he learnt at Spurs when he faces his old friends at the Nissan Stadium in Nashville on the final leg of City's US tour.
Walker also enjoyed a tussle with another old pal, Gareth Bale, during City's 4-1 win over Real Madrid and he said: "Seeing old faces is always good, I shared some special moments with Gareth at Tottenham so it was nice to see him.
"It was nice to get a win over them.
"I feel fit and feel strong I've been doing a lot of work off season, to keep up my fitness up.
"I'm just looking forward to the start of the season, we have two important games in pre-season to look forward to, get a few more minutes on the board. But it all counts when we go to Brighton and play them.
"It's going to be difficult (against Tottenham) I'm not going to lie. I spent a lot of years there, had special moments and the lads are great, the coaching staff is great and they helped me to get to where I am now.
"But it's a football match and I want to win so if we can go there and pick up a victory that would be fantastic."
