Bruno Fernandes admits Manchester United must "do better" after their embarrassing defeat against Istanbul Basaksehir piled pressure on boss Ole Gunnar Solskjaer.
United have endured a rocky start to the season and Wednesday's Champions League loss in Istanbul was the latest painful result for the under-fire Solskjaer.
Amid talk that Solskjaer could be replaced by former Tottenham Hotspur coach Mauricio Pochettino, Fernandes acknowledged United have been below their best over the last seven days, with Arsenal handing them a home defeat in the Premier League last weekend that left them close to the relegation zone.
While October started with a chastening 6-1 home loss to Tottenham, Portugal midfielder Fernandes believes United's Champions League victories against Red Bull Leipzig and Paris Saint Germain, as well as their comfortable Premier League win at Newcastle United, prove it is not all doom and gloom.
