We are just a few months into the season, but Manchester United look like they have the quality in their squad to mount a serious challenge for silverware across all fronts this campaign.

After a disappointing season last year where The Red Devils finished outside the top four, Jose Mourinho looks to have finally achieved a winning formula in Manchester.

A big part of their early season success must be attributed to their transformation in attack; Henrikh Mkhitaryan has been a revelation in midfield and Romelu Lukaku is promising goals on a regular basis.

As a result, Man United have won six of their seven Premier League games so far this season, with their only blemish being a draw away to Stoke.

They have also built up a mightily impressive goal difference of +19, largely thanks to four 4-0 victories already this term.

However, Manchester United may well be second favourites to lift the title this year due to the brilliance of their rivals, Manchester City.

And with the race to be champions set to go down to the wire, Mourinho has already started making plans to bolster his squad.

In order to compete with Pep Guardiola's men, United are reportedly interested in Napoli star, Dries Mertens.

The Belgian forward has been in fine form in recent years, having notched 34 goals in just 45 games last season, and he could be available for a cut price thanks to a release clause in his contract.

According to Calcio Mercato, former Napoli sporting director Pierpaolo Marino revealed in an interview with Tuttosport in reference to Mertens: "The €28 million clause is likely to be a tired price even if he is 30.

"It turns out that United is following him very closely."

With world-class forwards usually costing in excess of £50 million these days, Mertens' release clause is sure to draw interest from a host of Europe's top clubs.

The only issue would be his age; at 30-years-old the Belgian is no spring chicken.

However, given his versatility to play anywhere across the front three, as well as his incredible scoring record, Mertens could prove to be a bargain at that price.
