The tough-tackling Argentine has expressed his delight at the Baggies' recent chant in his honour, and wants to pay back their faith in him with good performances on the pitch
The 25-year-old Argentine joined the Baggies from Racing Club in the summer and has impressed in central midfield, as his side sit eighth in the Premier League with eight games remaining.
Yacob says he is happy in his usually unsung role in defensive midfield, and expressed delight that West Brom supporters have taken to him, with a new chant in his honour.
"I don't catch the attention like players such as Lukaku and Long, I don't score goals because that's not my role – but I think my function is very important to help the team achieve their overall goal," he told the club's official website.
"Scoring goals is the aim of the match but it's not the most important thing. I'm over the moon that I'm well thought of and I feel I want to give it back to the supporters as much as I can. I'm very happy and I like the song the fans have made up for me."
Yacob is also enjoying settling in at the club; he was effusive in his praise of his team-mates as, despite the Argentine's limited English, they have been very patient and accommodating.
He added: "The better my English gets the closer I get to the players, I can now have short conversations. It's very important I can mingle with the players and feel more comfortable.
"I like talking to the younger players because I realise how important it is for them to talk to me. It also gives me the chance to practice my English because they will be very patient. I'm very happy with all the players because they look after me."
