Arsenal are monitoring Watford striker Odion Ighalo ahead of a potential £20 million summer swoop, according to the Daily Mirror.
The 26-year-old has netted 14 times in 26 Premier League outings in what has been a successful top-flight return for the Hornets, who sit nine places and 13 points clear of the relegation zone with 12 games left.
With the Nigerian being contracted to Watford until 2020, Ighalo is unlikely to come cheap as the report states that Quique Sanchez Flores values his talisman at £20 million.
Arsenal fans would love to see genuine competition for Giroud, whose striking rivals in North London include Theo Walcott and Danny Welbeck - neither of whom are proven goalscorers from a central role.
The Frenchman, whose last goal came in the 3-3 draw at Liverpool on January 13, incurred the wrath of Gunners fans again following an indifferent showing in Tuesday's 2-0 Champions League defeat by Barcelona.
Ighalo, who has not scored in his last three league matches, will look to rediscover his red-hot form in front of goal when Watford host Bournemouth on Saturday.
