Lampard will try to address his defense problems in this transfer window, but Marcos Alonso may already have a solution to a problem.
Chelsea have been a little different lately. Frank Lampard's move to a 3-4-3 system aside from a 5-3 loss to champions Liverpool has proven to be an effective change.
For the most part, the blues are more solid defensively, less exposed when teams break and generally more organized. The impressive 3-1 win over Manchester United in the FA Cup final encouraged Lampard to stick to this new system, although his belief in losing to Anfield may have fluctuated slightly.
However, he stuck with it and there were plenty of positive signs as Chelsea beat Wolves with a 2-0 victory on the final day of the Premier League season and secured a top four spot.
There were nuances of the 2016-17 Antonio Contes winning squad last week, with Reece James on the right as Victor Moses and Marcos Alonso in his well-known left wing-back position.
The latter was particularly impressive against Wolves, as he quashed the significant threat posed by Adama Traore when he emerged from the bench and proved to be generally effective going forward. The Spaniard, now 29, is adapting perfectly to this system, which could give Lampard much to think about.
Alonso hasn't always been in the first team this season. He has only started 15 Premier League games and often looked shaky as a left-back in a four-man defense. However, his performance improved significantly when he operated on a back five. Three goals in nine appearances have come in as a left-back.
It remains to be seen whether Lampard will go for a long-term 3-4-3. In this case, Alonso may be the best option as he only knew the role and its importance during the Conte’s era few years ago.
It could solve Chelsea left-back's dilemma, despite Leicester's Ben Chilwell big money move and Ajax's Nicolas Tagliafico has also been linked with a move to Stamford Bridge.
If the Blues want to save the money to invest in other areas of the team, it could be a smart move. Although Alonso is often criticized and vilified for his defensive mistakes, he is more than capable of playing for a top Premier League side at a consistently high level, especially in a formation that shows all his strength.
Much will of course depend on how Lampard wants to play his team next season. If 3-4-3 were introduced as a short-term fix, Alonso's future could be in doubt. He turns 30 in December and has been linked with the likes of Sevilla and Inter Milan this summer.
Lampard won't want to be in too much of a rush to get rid of a player with Alonso's experience. The instinct of modern football is to spend a lot of money to tackle problems, identify exciting young talent and sideline top professionals.
Sometimes, however, the best option is to look within.
