Not signing Newcastle United star Bruno Guimaraes in January looks to be the latest transfer regret for Arsenal. The Gunners have lost their last three Premier League outings, with injured midfielder Thomas Partey clearly hugely missed in the middle of the park. That slump in form has seen Mikel Arteta 's side slide down to sixth in the Premier League table having been sitting pretty in fourth just a few weeks ago.
A large section of the club's fanbase have been blaming technical director Edu for their recent downturn in form, with the Brazilian transfer chief opting to not make any first-team additions during the winter window - something that has clearly cost the north Londoners in the last few weeks.
Tough-tackling midfielder Guimaraes was one player heavily linked with a switch to the Emirates Stadium before he eventually joined the Magpies instead.
