Arsenal fan Piers Morgan comments on Tottenham's new boss Pochettino

Tottenham Hotspur have announced a deal that sees Mauricio Pochettino leave Southampton to join Spurs.

Swapping Southampton for Spurs is a retrograde move on the part of renowned Argentinean football coach Mauricio Pochettino, according to social media savvy Arsenal supporter Piers Morgan.

Tottenham Hotspur and Pochettino agreed a five year deal, as confirmed by the club's official website earlier today, Tuesday, with chairman Daniel Levy looking forward to "high energy, attacking football [and Pochettino's proven ability to] build a great team spirit and winning mentality."

Pochettino, 42, who had a 38% winning record with the Saints having won 23, drawn 18 and lost 19 from 60 games in charge on the south coast, commented on the "tremendous history" surrounding the White Hart Lane club whilst also expressing his excitement at working with the "abundance of top class talent" at Spurs.

Tottenham finished the Premier League season in sixth place, two positions above Southampton in eighth who, with players like Luke Shaw and Adam Lallana, together with Pochettino, were a part of an exciting package seemingly capable continuing their march up the Premier League ladder when the next season stars, in August.

Morgan, whose Arsenal side claimed fourth spot, said: "[I] don't understand Pochettino's decision - why would he trade down?"
