Shaqiri's mentor at Switzerland, Ottmar Hitzfeld, had been Lambert's at Borussia Dortmund, back in 1997 when they won the Champions League.
He said: “I know he played under Ottmar Hitzfeld. Actually I didn't know that before… but I know it now! They won the Champions League together and I've spoken with the gaffer about that already.
“I've had a few conversations with him and I'm really happy he's here. It's a new chapter for the club and it's exciting.
“We've done a lot of work already. As a player you know exactly what he wants. He said to everyone what they need to do."
He added: “Of course a new manager changes things and I think you could see that from how we played against Huddersfield. It was totally different on the pitch. We communicated a lot, we pressed really high and the defenders stayed high."
