Former Leeds United striker Whelan told Football Insider: “He’s been at Tottenham a hell of a long time now, Erik Lamela, and he’s always been one of these players that is a go-to from the bench.
“He’s had short spells when he’s been a starter in the side, more so with Mauricio Pochettino.
“Now he’s the sort of player that, on his day, can be a world beater. He can score great goals, he’s fantastic with the ball on the deck, great pace, good eye for a pass.
“It’s a catch 22 situation.
