West Brom manager Tony Mowbray was full of praise for Arsenal's rookie Jay Simpson after the on-loan striker put the Baggies on the way to an FA Cup fourth-round home tie against Burnley.
Simpson dented Peterborough's hopes of a cup shock with an 18th-minute opener, his first for the club, and defender Paul Robinson made sure of an Albion victory with a second goal eight minutes before the break.
Mowbray said: "Maybe Jay Simpson's quality and ability to score goals like he did here will help us in the Premier League."
He added: "Our team needs help in the goalscoring department. It needs creativity, because generally, week-in and week-out, ball retention is not a problem for us.
"We can control games but if you can't stick the ball in the net you will not win. Let's hope Jay can do that.
"I saw Jay play against Wigan in the Carling Cup and give them a torrid time. Arsenal's kids ran them ragged and it was a strong Wigan team.
"Simpson looked such a potent threat and I thought that was something our team needed. There was an opportunity to bring in a player who wasn't quite ready for Arsenal. I am delighted they allowed us to take him.
"We saw at The Hawthorns how well Peterborough can play but I don't think they reached those heights.
"We felt that the first game was their best chance of getting through the tie. We came here twice last season and won so it held no fears for us."
