Ardent fans sit the entire day with a firm eye on the latest developments in the football market. Several big-money signings have occurred on deadline day in January in the last decade.While some have turned out to be fruitful, most players are deemed flops. This shouldn't come as a surprise, as most of these moves are panic buys. Here are the January transfer window's top five costly deadline day deals.#5 Juan Cuadrado - Fiorentina to Chelsea for €31.00mAston Villa v Chelsea - Premier LeagueJuan Cuadrado is among a plethora of wingers/attacking midfielders who couldn't make their mark at Chelsea. The former Fiorentina wideman was snapped up by The Blues during Jose Mourinho's second stint at Stamford Bridge between 2013-15.Cuadrado had a torrid time during his first season in the Premier League. Despite featuring in 12 Premier League games, he failed to score a single goal. The Colombian international spent a couple of seasons on loan at Juventus before sealing a permanent deal with them.Squawka Football@SquawkaJuan Cuadrado did not register a single goal or assist for Chelsea in 13 Premier League appearances. http://t.co/VttEaKDxbz7:39 AM · Aug 25, 201549124Juan Cuadrado did not register a single goal or assist for Chelsea in 13 Premier League appearances. http://t.co/VttEaKDxbzOverall, the winger, who has now turned into a full-back, played just 15 times for Chelsea. Despite facing stiff competition from the likes of Andriy Shevchenko, Kepa Arrizabalaga and Alvaro Morata, Cuadrado ranks among Chelsea's biggest flops.#4 Andy Carroll - Newcastle to Liverpool for €41 millionLiverpool v Everton - FA Cup Semi FinalLiverpool purchased Andy Carroll on deadline day of the 2010-11 winter transfer window. January 31, 2011, proved to be a busy day at Anfield. While Fernando Torres left Liverpool, Luis Suarez and Andy Carroll joined the Reds.Both Torres and Carroll were record-breaking signings for Chelsea and Liverpool, respectively. Ironically, Luis Suarez, who slipped under the radar at the time, was by far the best transfer. Carroll had a disappointing two-year spell with the Merseyside club.Anfield Watch@AnfieldWatchAndy Carroll on his time at Liverpool:"Liverpool was completely different. I should have embraced their ideas, what they wanted. Thinking back, I really didn't appreciate what I had and what I could have achieved." #awlive [the athletic]7:42 AM · Sep 17, 202142423Andy Carroll on his time at Liverpool:"Liverpool was completely different.

Thinking back, I really didn't appreciate what I had and what I could have achieved." #awlive [the athletic] https://t.co/gZmNKbOz5VThe Englishman scored just 11 times in 58 appearances for the Premier League giants. West Ham bought him in the summer of 2013 for €17.5 million, less than half the amount Liverpool shelled out for the striker in 2011. Carroll now plies his trade for West Brom in the Championship.
