Why is Lisandro Martinez not suspended for Man Utd vs Roma?

MANCHESTER UNITED fans breathe sigh of relif after discovering Lisandro Martinez will be available for their Champions League tie against Roma. The Argentinian picks up his second red card for United in the defeat to Chelsea as their poor run of form continues Just before the hour mark referee Peter Banks booked Martinez for a pull on Morgan Rogers shirt. Then just 83 seconds later, from a corner that came from the Freekick he gave away, Martinez runs straight into Wesely Fofana with his arm raised and caught the Chelsea defender in the face.
