Within the last seven days, the reigning Premier League champions have announced the signing of Abdul Rahman Baba from Augsburg, and Pedro Rodriguez from Barcelona.
While the duo are still settling into their new surroundings and may not be ready for a start, Mourinho’s half-time substitution of John Terry last weekend proves that the Portuguese boss is unafraid of making bold decisions early on in the new season.

The Daily Star report that Rahman could make a start at left back, with Cesar Azpilicueta switching to right back as question marks surround the form of – the usually reliable – Branislav Ivanovic.
Pedro would be a surprise inclusion in Mourinho’s XI, with the game against the Baggies arriving just two days after his confirmed move to Stamford Bridge.
Thibaut Courtois, meanwhile, will return in goal having served his one-match ban, despite Asmir Begovic’s impressive performance at the Etihad Stadium.
