Troy Parrott has described his Millwall loan spell last season as a “shock to the system”.
The Republic of Ireland international signed for the Lions on a season-long loan in August 2020 from Tottenham Hotspur.
He scored a brace in a pre-season friendly before picking up a quad injury that kept him out until late September.
When he did return to the side in September, the 20-year-old suffered another injury in the 2-0 defeat against Burnley in the EFL Cup.
Parrott had his loan terminated in January and moved to Ipswich Town for the rest of the season – leaving without scoring in a competitive match for Millwall.
Parrott told the Irish Examiner: “In a way, it was a little bit of a shock to the system.
“It just shows football is a weird sport. Anything can happen at any time and it’s just realising it’s not as easy as maybe I thought it was going to be when I was 16-17.
“It’s just the way things can change so quickly. Obviously, it’s a sport that we all love, but at times it can be crazy.
“You could be in one spot at one time and then a completely different spot in a matter of a day or a week. That’s where that was coming from.
“That’s another thing I’ve learned, not to get too high and not to get too low. You can be in two completely different spots at the snap of a finger. So it’s just trying to keep level-headed and sticking with it.”
