Unai Emery has admitted that he has a "big challenge ahead" after being tasked with turning around Aston Villa's fortunes.
The Spaniard took his first training session with Villa's players at their Bodymoor Heath HQ on Wednesday after receiving visa clearance. Emery, whose first game comes against Manchester United on Sunday, tweeted: "Day 1. Big challenge ahead. As big as the greatness of Aston Villa."
The ex-Arsenal boss and four-time Europa League winner has swapped Villarreal for a return to the Premier League to replace Steven Gerrard at Villa Park. Villa's owners want Emery to eventually deliver European football - but the immediate priority is ensuring 16th-placed Villa avoid being dragged into a relegation scrap.
