Derby County's manager Phillip Cocu has signed former Nottingham Forest attacker Jamie Paterson on a season-long loan deal from Bristol City for the 2019/20 campaign.

He moved to the Rams on the same day that Ben Hamer also signed for the club from Leicester City on a season-long loan deal, with the departure of Scott Carson to Manchester City for the remainder of the season.

Despite former manager Frank Lampard leaving for Chelsea, Derby have recruited a very good manager and have had a promising summer with several good signings. Krystian Bielik has arrived at Pride Park on a permanent deal after spending the previous season on loan at Charlton Athletic.

Fellow defender Matt Clarke also signed this summer, on a loan deal from Premier League side Brighton and Hove Albion and impressed in the Rams' 2-1 away win at recently-relegated side Huddersfield Town last weekend.

However, Wayne Rooney was arguably the most eye-catching signing of the summer for owner Mel Morris and Derby County, signing from DC United. He will join the club on an 18 month deal in January 2020.

Paterson was Cocu's last signing of the summer and it's now down to the Dutch coach to get the best out of his players. Here are two pros and two cons to Derby County's deal for the Bristol City man...

Pro: Versatility in his armour

Paterson can play right across the front line for Derby County, which will be of great use to the East Midlands club when they get injuries or suspensions.

Even though it's vital that Derby County have quality players in abundance if they want to go one step further this season in the Championship, it's also important that they have the depth required to play strong teams in all 46 of their Championship games.

Financial Fair Play and inflated Championship player wages has meant that it's often hard to get the depth needed in a squad without having to resort to using inexperienced youth players, some of whom aren't quite ready for the challenge of playing in the Championship. Having Paterson, who can play in several positions, will help this.

Pro: Vast experience of the Championship

Jamie Paterson has played in the Championship regularly for three different clubs: Nottingham Forest, Huddersfield Town and parent club Bristol City. Despite having all of this experience, Paterson is still only 27, in the peak years of his career.

He's played in over 80 Championship games for Bristol City over the past two seasons, which will be very encouraging for Phillip Cocu who needs his players to stay injury free if they want to achieve promotion this season.

Bristol City's loss will be Derby County's gain in terms of the winger.

Con: May not take Derby to a different level

Paterson has never played in the Premier League before and isn't necessarily identified as one of the Championship's best players. After Derby County's play-off defeat to Aston Villa last season, they are in desperate need of a player to take them to the next level.

Even though Jamie Paterson is a very good player, he's not exactly someone who will be able to do this on his own for the Rams. He's just another cog to Derby's machine.

Former England international Wayne Rooney may be that key player that Derby County need this season. However, he's signed a deal with Derby County that means he arrives in January 2020 instead of this summer.

Con: They're developing a player for a rival Championship side

Even though this might be quite a cheap deal for Phillip Cocu, what Derby County are doing is effectively helping Bristol City in developing Jamie Paterson. If this was a permanent deal for Paterson, Cocu could increase his value for Derby County's gain.

However, this loan may just help Bristol City in increasing his value if he does play well for Derby County. In this loan deal, Derby may also be parting a percentage/all of his wages.

With these wages, Derby County could have signed a free agent or promoted one of their younger players instead. It'll be interesting to see whether this move works out for Derby County, or whether it was just a beneficial move for Paterson and his parent club.
