Danny Guthrie has praised manager Gary Megson for the signings he made for Bolton Wanderers last month.
"The new players have helped freshen things up," the on-loan Liverpool midfielder said. "It keeps you on your toes, knowing someone is gunning for your position.
"Tomorrow's match (against Atletico Madrid) is a massive one for us and our supporters.
"Hopefully, we can get a good result so we're still in with a chance for the second leg."
