Championship side Watford appeared to have turned back the clock by signing Bergkamp and Pochettino – but it wasn’t the Arsenal legend or the former Argentina defender who made the move to the Hornets. It was their sons.

Midfielder Mitchel Bergkamp, 22, joined the club on a six-month contract while winger Maurizio Pochettino, 19, signed on a free transfer after leaving Tottenham.
