Frank Lampard has insisted he will never follow Jose Mourinho's lead and manage Tottenham.
Chelsea boss Lampard believes Tottenham are still a top-four threat for the Premier League this term, despite Spurs languishing down in 14th place after 12 matches.
Mauricio Pochettino was sacked this week and two-time Chelsea boss Mourinho jumped straight into the hot seat at the Blues' bitter rivals.
"It's a great test tomorrow, head to head, to see where we're at.
"But anyone can go to Manchester City, play at their best and still and lose.
"So I won't be making huge judgements win or lose tomorrow without a doubt.
"Our story is three months in the making. Their story has been four years and more of hard work from top to bottom."
