Newcastle, United Kingdom: Pep Guardiola refused to be drawn into a war of words with Jose Mourinho after Manchester City maintained their impressive progress towards the Premier League title.
City stretched their commanding advantage at the top to 15 points over Manchester United as Raheem Sterling sealed a 1-0 win at Newcastle to record an 18th consecutive league victory, one short of Bayern Munich's current best for Europe's top five leagues of 19 straight wins.
United manager Mourinho attempted to provoke Guardiola on Tuesday after pointing to their rivals' huge spending power by claiming "City buy full-backs for the price of strikers" and insisting that the £300 million ($402 million) he has spent since taking charge at Old Trafford 18 months ago as "not enough".
Mourinho paid £93 million to sign France midfielder Paul Pogba, while also recruiting £30 million defender Eric Bailly, and midfielder Henrikh Mkhitaryan for £26.3 million.
This year, United spent £75 million on striker Romelu Lukaku, as well as £31 million on defender Victor Lindelof and £40 million for midfielder Nemanja Matic.
In comparison, City bought three defenders -- Kyle Walker from Tottenham for an initial £45 million, Benjamin Mendy from Monaco for £52 million and Danilo from Real Madrid for £26.5 million as part of a summer outlay that topped £200 million.
When asked about the comments made by the Portuguese, Guardiola said: "I'm so delighted to be here to speak about what happened on the pitch.
