The 23-year-old US international is reportedly being chased by a number of European clubs.
Zardes, 23, joined the Galaxy as a Homegrown player in December 2012 but scored just four times in 27 games during his first season in MLS due to spending most of his time on the flanks.
The California-native experienced a spectacular 2014 campaign after moving into a more comfortable role up top, however, finishing the regular-season as the league’s second-highest American scorer with 16 goals in 32 appearances.
Going on to help LA claim their third MLS Cup title in four seasons, his promising performances have since earned him a regular spot in the US national team and now led to rumours that he could be set for a summer move to Europe.
Belgian outfit Genk were named as a potential suitor earlier this week [h/t HLN], while MLSsoccer.com have now claimed that Reading have joined a growing list of clubs that have registered an interest in the 13-times capped forward.
The report of the Championship side’s interest also comes after manager Steve Clarke stated that he was looking to add another striker to his squad ahead of the summer transfer window closing, telling getreading.com: “We've had 14 players out from the end of last season, including loans, and only eight back in, so you can see that there is room to bring a few more in.
"I'm still in the market for a striker. We're still looking, but it’s not easy. They are very expensive and we don't have a lot of money to go and get them."
Blessed with a tantalising combination of size, speed, strength and skill, there is a strong argument to make that Zardes possesses all the qualities of a Premier League front man but, at the same time, it is clear that he needs to work on the mental side of his game before he is prepared for that stage.
The 6ft 2in attacker, who has five goals in 21 MLS games this term, has been getting valuable lessons about what it takes to succeed in the English top-flight from club captain Robbie Keane in the meantime, though, while his strike-partner has also been quick to talk up his talent on a regular basis.
“He has come on a lot,” Keane told MLSSoccer.com when discussing Zardes’ progress during pre-season. “He played on the left [wing] in the first half, but striker is certainly his best position. He scored a lot of goals last year  and he’s only growing with being called up the national team as well.
“He’s certainly got the potential [to excel in Europe], but we want to keep him here.”
Nevertheless, LA might not have much choice if Reading come in with an enticing enough offer and, having bolstered their attack with the recent additions of Steven Gerrard and Giovani dos Santos, head coach Bruce Arena also seems to have enough cover to cope with his potential departure.
MLS clubs in general have never been reluctant to sell promising talent if a big European offer comes in and Reading would present a great chance for Zardes to make the next step in his career without being overwhelmed – unlike DeAndre Yedlin at Tottenham Hotspur.
The Royals already have USA teammate Danny Williams on their books, as well as fellow American Andrija Novakovich breaking through into the first-team, and adding the MLS All-Star to that group would be a wise move on the club’s part.
