Loan signings seem to be the flavor of the window with seemingly every transfer having an initial loan move involved. It allows the player time to settle into his new club. The club acquiring his signature has time to see if he actually fits into the team, in line with the club and the manager's philosophy. The loaning club have the opportunity to give their player some much-needed game time and also get his wages off of their books.That being said, here's a look at the top 5 loan signings this January:#5 Denis Suarez- ArsenalArsenal fans almost had a grim transfer window. Club owner Stan Kroenke was accused of being more interested in his other sports investment, the LA Rams who are on the cusp of winning the Super Bowl. Kroenke, the man who engineered the team's move to a new stadium while Arsenal was said to have no money to sign players, had to resort to loan signings to plug the holes in their squad.Given the restrictions on the club, Arsenal did get a great player on their hands. Former Barcelona man Denis is an astute midfielder who has the potential to take over the Number 10 spot as Emery tries to phase Ramsey out of the team. Clever on the ball with a knack for finding himself in small pockets of space around the box to create scoring opportunities, Denis Suarez might just prove to be a shrewd piece of business.An option to buy is present in the deal which Arsenal should look to make permanent if the player thrives at his new club. Having worked with Emery in the past, the player knows the system and the manager knows how to get the most out of him. If Denis hits the ground running in England, Arsenal would be strong contenders for a top-four finish.
