Phil Parkinson has rotated his side in recent weeks to cope with the demands of a busy fixture programme, and the games also come thick and fast for Chelsea who are chasing success on three fronts.
Liam Rosenior's side have three matches in the space of eight days, starting with Wednesday night's trip to Aston Villa in the Premier League.
It's a crucial game for Chelsea who are down to sixth in the top-flight after losing 2-1 at Arsenal on Sunday, and need a top-four finish to guarantee Champion's League football next season.
The Blues are back on the road at Wrexham on Saturday when the teams will battle it out for a place in the quarter-finals of the famous cup competition.
Chelsea have another away match next Wednesday when they head to Paris Saint-Germain for a Champions League last 16 tie.
That is arguably the biggest of the three games for Chelsea, although they are all important in their own right, and Rosenior is set to utilise his squad in the hat-trick of outings.
But whatever side he picks against Wrexham, it is bound to strong and oozing quality as Chelsea aim to avoid an upset.
