Manchester United captain Antonio Valencia insisted he is “fully supportive” of Jose Mourinho after appearing to back calls for the under-fire manager to leave.

All is not rosy at Old Trafford and a winless run stretched to a fourth game on Tuesday as Spanish visitors Valencia held United to a 0-0 draw in the Champions League.

Struggles on the field are compounded by issues away from it, with reports that skipper Valencia is not seeing eye-to-eye with Mourinho fuelled after the game.

The 33-liked-old ‘liked’ an Instagram post from a fan account which said that “recently Mourinho has made watching us a punishment” and “it’s time for Mourinho to go”.

Wary of the media scrutiny it had caused, as well as the manager’s argument with Paul Pogba about social media last week, Valencia attempted to explain and apologise on Wednesday morning.

“Yesterday, I liked a post on Instagram without reading the text that accompanied the picture,” the right-back wrote on Twitter.

“We are all giving our everything to improve the results.”
