The 33-year-old Netherlands international scored nine goals and added four assists in 34 Ajax appearances last term, a return that has attracted attention from clubs looking for an experienced, physical centre-forward who can contribute at a high level.
According to Diario AS, Real Betis and Celta Vigo are the two Spanish sides showing the keenest interest in Weghorst. The Andalusian club and the Galicians would both represent a return to Spanish football for the Dutchman, who has previously played in the Bundesliga and the Premier League in a career that has taken him across Europe's major leagues.
Benfica add a Portuguese dimension to the pursuit, giving Weghorst a range of options as the summer window opens.
With clubs in Spain and Portugal both in the picture, Weghorst has genuine choices about where he plays his football next season. The strength of interest from two La Liga sides in particular suggests the former Netherlands international still has the quality to attract attention from competitive European leagues at 33.
At 33, Weghorst is unlikely to command a significant transfer fee, which may work in the favour of clubs looking to add proven quality at a manageable cost. His physical presence and ability to hold up play represent a profile that appeals to teams who need someone capable of leading the line in a direct, high-intensity system.
Real Betis and Celta both finished in the top half of La Liga last season and will want to add firepower ahead of a campaign that for Betis will include European football. Weghorst's experience at the highest level gives him credentials that suit the ambitions of either club.
