Mido worked under Southgate for three years at the Riverside prior to the former England defender’s sacking in 2009, with the club languishing in the Championship.
And ex-Zamalek boss Mido has since reacted with disbelief to reports suggesting that Southgate could succeed Roy Hodgson, who resigned as manager following Monday’s chastening 2-1 defeat against Iceland in the last-16 of Euro 2016.
“I can’t believe that in England they are talking about Gareth Southgate to become the new manager! I hope he learned since the Boro days,” he wrote on Twitter.
Middlesbrough were relegated under Southgate’s management in the 2008-09, and embarked on a dismal run of just one win in 18 games.
However, Southgate has endured moderate success with the England Under-21 team, leading them to the European Under-21 Championships in 2015, though they finished bottom of their group in the tournament.
