Grimes said: “I thought we played well, we’ve been beaten by real moments of quality and a mistake at the end when we’re chasing it.
“We spoke about starting the second half quickly because you could hear a few moans and groans even when they were one-nil up.
“Conceding the second was disappointing, even then it felt like the game was only going to finish two-two and then we get dealt a sucker punch at the end.
“You can see in the last couple of games, the lads are really taking to [the Premier League] now and we’re starting to believe we belong at this level.
“It’s chalk and cheese from the Arsenal game at the start of the season, you can see the belief and confidence the lads are playing with.
“We just need to keep building, keep our feet on the ground and keep working hard. It’s all about learning and adapting.
“I’m enjoying it [in the Premier League], it’s a lot of change after playing so many years in the Championship but we’ve really grown into it.”
