Odion Ighalo has expressed his gratitude to Watford's supporters upon his exit from the club.

The Nigerian striker has joined Chinese Super League club Changchun Yatai in a £20million deal.

"A special thanks to Watford fans, who I really hold dearly in my heart because they supported me since the very first day I came to this club to the last day," Ighalo, who spent two-and-a-half years with the Hornets, told Sky Sports News HQ.

"Even when things weren't going well for me they were still there chanting my name beside me.

"Though things don't always go the way you want in life you have to keep moving and working hard."
