Spurs announced Senesi had signed on a free transfer on Wednesday after he left top-flight rivals Bournemouth at the finish of last season following the end of his contract.The 29-year-old Argentina centre-back joined Bournemouth in 2022 from Dutch club Feyenoord and played 128 times for the Cherries, but decided against a new deal with the south coast club and has instead moved to north London side Spurs."It's a very special feeling to be a Tottenham Hotspur player," Senesi said."From the first moment, the club has shown why they want me and how much they want me to be a part of what they are building. It's exciting and something I can't wait to be involved in."Italian manager De Zerbi oversaw Spurs' ultimately successful bid to avoid relegation from the Premier League with an 11-point haul during seven nervous matches, and he is now looking to bolster their porous defence.Tottenham have conceded 122 goals across the last two Premier League seasons, finishing 17th -- just above the relegation zone -- on both occasions.Their signing of ball-playing defender Senesi follows left-back Andy Robertson's arrival on a free transfer from Liverpool."Marcos's experience, quality on the ball, and competitive edge will strengthen us defensively, as well as giving us flexibility in formation," said De Zerbi."He's comfortable playing in a possession-based team, reads the game very well and has the personality to thrive in a demanding environment."I also love his mentality and desire to keep improving and I'm looking forward to working with him and seeing the big contribution he can make to the team."
