Manchester City remain unbeaten after beating West Brom 3-2 at the Hawthorns.The league-leaders certainly look like favourites for the Premier League title despite Manchester United closing the gap at the top with a 1-0 win over Tottenham.It's fair to say Pep Guardiola is under some pressure to deliver silverware in his second season in charge.Having spent £217.3million in the summer, City look a well-oiled machine and the arrivals of Kyle Walker has been particularly key.The former Tottenham defender has five assists in all competitions, dispelling any doubts about the club spending £50m on him.If City's attack wasn't already frightening enough, they've now got one of the most energetic, enterprising full-backs in English football.Gary Lineker was one of his more outspoken critics when he quit north London to move to the Etihad, having a joke at Walker's expense about his crossing ability.

Last season, Walker had more assists than any other full-back in the league, so that comment was probably a little harsh.

Walker definitely can cross 

Lineker has been reminded of it ever since, prompting him to tweet again after the 27-year-old's latest assist:

Of all the defenders City signed, Walker has been having the most immediate impact, not least because Benjamin Mendy has been sidelined through injury.

The England international formed a formidable partnership with Danny Rose at Spurs and it didn't look like he could get much better.

Towards the end of last season, he fell out of favour with Mauricio Pochettino and it quickly became clear he was going to seek a new challenge under Guardiola.

The City boss' only real criticism after the West Brom game was that his side didn't take enough of their chances, which could have backfired as the Baggies attempted to stage a late comeback.

He can have had no complaints with his players for their creativity, as once again they looked absolutely scintillating going forward.

Is Walker the best right-back in the Premier League? Have your say in the comments.
