West Brom assistant boss Peter Grant says the loss to injury of Ishmael Miller was a big blow.
"At the time Ishmael got his injury, he was starting to find his feet in the Premier League," Grant told the Birmingham Mail. "If you look at the chances he had at Middlesbrough, he had three or four one-on-ones.
"But in the two or three games prior to the injury he was starting to look like a Premier League player.
"He was understanding what the Premier League was all about so losing him was a massive blow for us because he is different to what we have with his power and pace.
"And the opposition were worried about him. It's a great thing to have as a striker if the opposition are worried about you and he was starting to prove that.
"When you don't have a massive squad like a Manchester United, it can become very difficult when you lose big players."
