June's takeover by the Pozzo family led to the appointment of Gianfranco Zola as manager before as many as 16 new players were brought in, the majority of whom on loan from either Udinese or Granada, clubs also under the control of Watford's new Italian owners.
Two wins from the opening nine games of the season did not paint a pretty picture but the Hornets have now flown up to eighth place in the table, just two points off the top six, on the back of just three defeats in their last 13 matches.
Midfielder Hogg, also at Vicarage Road last season, has been a mainstay of Zola's team, and he said: "I think with the amount of changes that happened to the club with all the players coming in, there's been so many changes. I didn't think so many changes in one season would happen but the lads have started to settle down now, started to find their feet."
"Coming from all the different countries, it's obviously going to be hard getting used to the game (over here) but now they've played games in the Championship they're finding out what it's all about."
Hogg added: "It was really difficult at the start because we didn't know what was happening, we couldn't understand them, they couldn't understand us, but now they've had a lot of English lessons and they're starting to pick up bits and bobs of the language. The more games they play in the Championship the better they're going to get at this level because they're great players."
