Is David de Gea still a world class goalkeeper?
When does a blip go beyond a blip?
On the latest episode of Liquid Football, Kelly Cates is joined by former Birmingham and West Ham defender Matthew Upson, and ex-Aston Villa playmaker Lee Hendrie.
After a weekend which saw champions-elect Liverpool suffer their first league defeat of the season, the panel discuss their loss to Nigel Pearson's Watford and wonder if the defeat will effect Jurgen Klopp's side in any meaningful way, especially as they enter a period of crucial ties against the likes of Chelsea and Atletico Madrid.
It was another weekend which featured a now not that uncommon error from Manchester United goalkeeper David de Gea, which leads the panel to ponder whether the Spaniard is world class anymore and, indeed, if these mistakes are still blips or simply a part of his game?
Should he be dropped and Dean Henderson installed as number on next season? It's all discussed.
Manchester City claimed their third League Cup in a row against Aston Villa at Wembley, but Dean Smith's team were praised for their efforts, which saw them push Pep Guardiola's team all the way to the final whistle.
Will this performance help Villa with their fight against promotion? And beyond that, is it time for Jack Grealish to look for a move away from the club to evolve his game further and win trophies.
Also up for discussion is Wilfried Zaha, who was subject to mocking gesticulations from Brighton players over the weekend. Does the Crystal Palace talisman get harsh treatment and could he deal with it better?
