West Ham United boss Gianfranco Zola was delighted with the performance of Guillermo Franco in their 3-3 draw at Hull City.
The Mexico international arrived in east London on the back of a strong run of goals for his country and played a pivotal role in their qualification for South Africa in the summer.
Zola told whufc.com: "Franco has been very good for me. I was certainly surprised that Villarreal didn't give him a contract but maybe there was something else there. He's proving to be a very good player for us. He's been a very good gain for West Ham United.
"He is an excellent guy, he works very hard and, above all, he's a very intelligent player. He does that right things for the team and I'm really impressed with him."
