Walker quits Twitter after abuse
After the game he posted two angry tweets before deleting his account @kyle28walker, which had over a quarter of a million followers.
"Would love to know what I'm doing so different I give 100% every game and still u (have) something to say I'm 22 and learning #embarrassing," he tweeted.
The England defender often looked vulnerable against Mata, and his cohorts Oscar and Eden Hazard, and was criticised by fans at the stadium and on Twitter as a result.
He added: "If I said what I thought to these people I would get done humans make mistakes it was 90mins and I though(t it was) a foul end off (sic)!!!!"
The 22-year-old was named the Professional Footballers' Association Young Player of the Season last term, but has not been as consistent this year.
One player who was in a much happier mood after the game was Chelsea left-back Ashley Cole, who was booed throughout the clash in north London. The former Arsenal player ended a turbulent week on a high as he helped his team stretch their unbeaten Barclays Premier League run to eight games.
This week Cole received a record Â£90,000 fine for labelling the Football Association a "bunch of t**ts" in the wake of claims the left-back did not tell the truth at the John Terry race abuse inquiry.
The 31-year-old, who is often the brunt of abuse from opposing fans, made sure had the last laugh against those who heckled him today, posting: "Why all you spud (Spurs) fans coming for me now, little to (sic) late aint it, I didn't know hell was silent!!!!! #CANTWAITTOGOBACK."
