Arthur Masuaku has left West Ham United today in order to join Besiktas on loan.

What's the talk?

That's according to the club's official channels, who reveal that the left-back has now joined Besiktas JK on a season-long loan deal, with the Turkish side possessing the option to make the 28-year-old's switch a permanent one at the end of the 2022/23 campaign.

The Evening Standard has since suggested that the club are hoping to bring Eintracht Frankfurt wing-back, Filip Kostic, in as the defender's replacement.

However, with the 29-year-old said to be unsure as to whether he would be open to a move to the London Stadium this summer, the Hammers boss is believed to be keen to pursue other options in the position, with the new Premier League campaign fast approaching.

Moyes must now act

Considering just how unpredictable Masuaku has been for West Ham ever since his £6m move from Olympiakos back in the summer of 2016, the news that the 28-year-old is finally on the way out of the club is sure to come as a relief for many involved with the Irons.

This is an opinion it would appear supporters of the Hammers agree with, as the overwhelming majority revealed in a poll ran by Football FanCast that they feel the club should move the 11-cap international on this summer - and it is not difficult to see why.

Indeed, the £4.5m-rated left-back failed to cement a starting spot in the Hammers' side over the past six years, starting just 79 Premier League fixtures since his move to east London - an average of 13-per-season - as well as making a further 26 appearances from the bench.

In terms of his level of performance when called upon, the results do not make pretty reading for the £43k-per-week defender, with the player who one West Ham analyst dubbed "terrible" averaging a disappointing SofaScore match rating of just 6.74 over his six top-flight campaigns for the Irons.

As such, with Moyes' side undoubtedly once again hoping to mount a charge on the top six in the league in 2022/23, in addition to making a mark in their first ever Europa Conference League campaign, it is clear to see that an upgrade is required on the left of the Hammers' backline - especially with Aaron Cresswell set to turn 33 later this year.

And, while the €22m (£18.5m) signing of the 67-goal and 102-assist Kostic would certainly represent a remarkable piece of business for the Hammers this summer, with the Serbian stalling and West Ham due to kick off the new Premier League campaign against Manchester City in five days time, Moyes simply must make a decision on the 29-year-old in the coming days - be that going all in for the Frankfurt star or making a move for another target in the position.
