While Andre Villas-Boas and his men lament their club's form in Bordeaux, the authority of PSG boss Thomas Tuchel will be under the spotlight at the Stade Beaujoire on Tuesday night after a show of petulance from star striker Kylian Mbappé on Saturday during the 5-0 waltz past Montpellier.

"There are other players who have worked hard and deserve a chance to show their abilities."
