The Baggies triumphed 4-0, with Lambert scoring the opening goal via a deflection before netting his team’s third early in the second half against his former team. He was substituted in the 56th minute to great applause from both sets of fans.
Lambert, 33, moves to the Hawthorns after just one season at his home-town club Liverpool where he rarely started first-team games.
“It was important we signed him early enough for him to get some game time, because he needs game time,” Pulis told Sky Sports News HQ
“As you’ve seen today, with the goals he scored, he’s got the quality in the final third that we’re looking for.
“And he’s a good lad. He’s an important signing for the dressing room. He’s on less money than he was at Liverpool, so he wants to play football.
“It’s important to get players like that, who want to come and play. He’s a player of great pedigree and we look forward to integrating him into our squad.”
Lambert told Sky Sports News HQ that there were other clubs interested in signing him but that he always felt that West Brom would be an ideal fit.
He said: “There were other clubs interested but from the get-go West Brom just stood out for me. Tony Pulis played a big part in that and I think he can be good for me and I can be good for West Brom.”
Lambert has signed a two-year contract with Liverpool reportedly losing around £1m on the deal. He only passed his medical on Friday before travelling to Bristol to make his debut.
